+        almost all of the time.  The one case where they would fail
+        regularly (inferior Scheme) has been bypassed by using pipes.
+

+        is exactly 1 does it mean it found something.
+
+        * sysdep.c (creat_copy_attrs): Downcase remaining SYS$OPEN, SSY$CLOSE.

+
+        * x11term.c (x_term_init): Comment out fatal error which prevents
+        X11 interface from being used if interrupt_input is false.  This
+        is unnecessary and untrue -- the interface works, but
+        suboptimally.
+
+1988-04-19  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
+
+        * sysdep.c (sys_access) [VMS]: If arg is dirname, cvt to name as file.

+        (stufflines): Restore signal mask only once, at the end.

+        Never change any other mask bit.
+
+        * x11term.c (internal_socket_read): Initialize COUNT.
+
+        * ymakefile (LIBX): /usr/X11/lib/oldX/liboldX.a becomes -loldX.

+        (define_logical_name, delete_logical_name): New fns to make
+        job-wide logical names.  "This is more useful for communicating with
+        other processes, since when Emacs is run in a subprocess (as it
+        usually is), the others see job-wide logical names, not DCL symbols)."
+
+1988-04-09  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
+
+        * ymakefile: If UNEXEC is defined, it specifies object file for unexec.

+
+1988-03-29  Richard M. Stallman  (rms at wilson)

+
+        * s-usg5-3.h: #define close sys_close (like open, read, write).
+        * sysdep.c: Undef `close', like `open'.
+        * sysdep.c (sys_close): New function.
+        All refs to close in sysdep.c renamed to sys_close.
+

+        since an array is always nonzero as a pointer.
+
+        * filelock.c: Include config.h after sys/stat.h so can undef S_IFLNK.

+        Don't alter cursX.
+
+1988-03-23  Richard M. Stallman  (rms at wilson)
+
+        * x11term.h: Use X11/ not X/ for dir of include files.
+        * xmenu.c: Likewise, in the X11 case.
+
+        * m-7300.h: Fix unterminated comment near end.
+
+        * s-xenix.h: Define n_zeroes so usage of struct nlist in fns.c works.

+
+        * sink11.h, sink11msk.h: New files.

+        Don't define X11 since this is included only if X11.
+
+        * x11term.c: Use sink11.h and sink11msk.h, not sink.h and sinkmask.h.
+        Don't define CLASS.  Delete everything about BIGDEBUG.

+        (XXidentity): now global.
+        (CursorOutline): New var; nonzero means cursor is hollow.

+
+        * process.c (wait_reading_process_input):
+        Use only detect_input_pending to check for pending kbd input.
+        (That `select' saw something on channel 0 doesn't mean it is
+        kbd input; it could be an expose event.)
+
+        * keyboard.c (read_avail_input) [FIONREAD]:  Now static.
+        New arg specifies value of NREAD;
+        if it is nonzero, don't call get_input_pending to get it.
+        Use kbd_buffer_store_char to put chars into kbd_buffer.
+        Always abort if kbd_count is nonzero at start.
+        Don't call {set,clear}_waiting_for_input.
+
+        (get_input_pending): Now static.
+        Return immediately if kbd_count > 0 or if Vquit_flag is non-nil.
+        If FIONREAD and not interrupt_input and read_socket_hook,
+        call read_avail_input to see how much pending input is really
+        kbd characters; don't say we have some if an expose event is pending.
+
+        * dispnew.c (init_display): Check result of egetenv for emptiness
+        as well as nullness.
+

+
+        * buffer.c (Fbuffer_local_variables): The buffer's alist can be out

+        the alist up to date.
+
+        * sysdep.c [VMS] (end_kbd_input): If ast_active, don't clobber
+        any global variables.
+
+        * ymakefile (alloca.o): Copy sed output to a .s file and use cc
+        to run the assembler.  I hear Xenix can't run it directly.
+
+        * sysdep.c [XENIX]: Undefine TIOCGETC.
+
+        * s-xenix.h: Undefine NLIST_STRUCT.  Put `_' in defn of LDAV_SYMBOL.

+        kbd_count should be 0.  Can happen on V.3.
+
+        * x11fns.c (Vxterm1): Delete this variable, and lisp var `xterm'.
+        (syms_of_xfns): If CANNOT_DUMP and not `noninteractive',
+        init_display has already set up Vxterm, so don't init it here.
+        * display.c (syms_of_display): Likewise for Vwindow_system.
+        (init_display): Always set Vwindow_system.

+
+        * s-hpux.h, m-hp9000s300.h, m-hp9000s800.h: Version 6.01 of HP-UX
+        (on 300 machines only) implements symbolic links and supplies BSD
+        procedures like `bcopy' and `index' as part of the BSD library.
+        Move definitions which depend on these features from the s- file
+        to the m- files, and conditionalize the features based on a flag.

+
+        * buffer.c (init_buffer): If `getwd' fails, it's a fatal error.
+
+        * ymakefile (MAKE_PARALLEL): New name for PARALLEL, and now
+        a cpp macro, not a Make variable.  Defaults to empty.
+        * m-sequent.h: Define MAKE_PARALLEL.
+
+        * xdisp.c (display_text_line): Handle the overlay arrow last of all,
+        and update line->length for the space it uses.
+
+        * xmenu.c: Conditionals for X11, using new macro X11ONLY.
+        Currently named x11menu.c until someone tests it.
+        * ymakefile: Handle HAVE_X_MENU and use xmenu.o, even if X11.
+        * x11term.h: Define BLOCK_INPUT, UNBLOCK_INPUT, BLOCK_INPUT_DECLARE.
+
+        * Makefile: Set $(MAKE), since some Make versions don't have it.
+        (xmakefile): Delete lines that are just one OR MORE whitespace
+        chars.  Use \t to represent the tab in the `sed' command.
+
+        * fileio.c (Finsert_file_contents) [APOLLO]: Do another `stat'
+        after closing the file.  Gets around kernel bug (in `fstat'?).
+
+        * fileio.c (Fwrite_region) [ALLIANT]: Don't do `fsync'; kernel bug.
+
+        * sysdep.c (sys_suspend): If forking shell, call close_process_descs.

+
+        * sysdep.c [VMS]: Remove VMS4_6 conditional on execvp & rename
+        since s-vms.h is set to make us use our own definitions of these.
+        Make execvp call `error' instead of `croak'.
+
+        * s-vms.h: PURESIZE 132000.
+        * m-sun2.h: Likewise (for HAVE_SUN_WINDOWS).

+
+        * callproc.c (child_setup): Call close_process_descs
+        if can have subprocesses.  Close the argument-descriptors

+
+        * callproc.c (Fcall_process): After fork, in subprocess,
+        explicitly close Emacs's end of the pipe.  Don't bother calling
+        set_exclusive_use.
+
+        * process.c (close_process_descs): Close all descriptors
+        that are talking to subprocesses.  Called from a new subprocess.
+
+        * process.c (create_process): Don't bother calling set_exclusive_use
+        since close_process_descs now closes Emacs's side of a pipe or pty.
+
+        * x11term.c, x11fns.c, x11term.h: New files from rfrench@athena.mit.edu
+        In x11term.c, the function `read_events_block' has been `if 0'd
+        and so have all calls to it.  A call in wait_reading_process_output
+        was not added, and a call to internal_read_socket in
+        get_input_pending was not added.
+
+        * emacs.c (main) [HAVE_X_WINDOWS]: Set xargv, xargc for xterm.c.
+
+        * dispnew.c (init_display) [X11]: Set Vwindow_system to `x11'.
+
+        * s-hupx.h: Define HAVE_SYSVIPC.
+        Should s-usg*.h define this too?
+
+        * dir.h: Some union types were missing levels of struct inside them.
+
+        * alloc.c (Fpurecopy): If not purifying, do nothing.

+
+        * sysdep.c (init_sys_modes) [USG]: Set C-g for VQUIT as well as VINTR.
+        This was formerly done only on HPUX, and worked there.
+        It appears that all sysV is like HPUX in that CDEL does not
+        really turn off the signal--it makes Meta-DEL cause the signal!
+
+        * process.c (wait_reading_process_output): Change the test on
+        read_kbd to avoid losing on 80386 Xenix.

+        This is enabled by the switch HAVE_SUN_WINDOWS.
+
+        * m-sun2.h: If HAVE_SUN_WINDOWS, include sunfns.c
+        via OBJECTS_MACHINE and SYMS_MACHINE.
+
+        * emacs.c (main): Allow SYMS_SYSTEM and SYMS_MACHINE
+        to control calling of extra syms_of_... functions.

+        files to link into temacs.
+
+1987-03-12  Richard M. Stallman  (rms at prep)
+
+        * fileio.c (Fsysnetunam): Make this function conditional on
+        HPUX_NET, not on HPUX.
+        * s-hpux.h: Make use of -ln switch depend on HPUX_NET.
+        Define HPUX_NET in config.h if you have that version of HPUX.
+
+        * unexec.c (adjust_lnnoptrs) [amdahl_uts]:
+        Alternative names for struct symentry and struct auxentry.

+
+        * sysdep.c (child_setup_tty):
+        HPUX: Set baud-rate to 9600 (not 38400)
+        For some reason the former is reported to work faster(!?)
+
+1987-03-10  Richard M. Stallman  (rms at prep)
+
+        * dispnew.c (init_display): Declare alternate_display only if X.
+
+1987-03-09  Richard M. Stallman  (rms at prep)
+
+        * m-alliant.h, crt0.c for alliant:
+        Must save _curbrk when dumping (from ADJUST_EXEC_HEADER)
+        and restore it in crt0, because _curbrk itself isn't dumped.
+
+        * unexec.c: Add a separate unexec routine for mips machines.
+        No code is shared with normal unexec.
+
+1987-03-08  Richard M. Stallman  (rms at prep)
+
+        * sysdep.c (baud_convert): Use new macro BAUD_CONVERT
+        to override the standard conversion table.
+        Use standard table if macro's not defined.
+        * s-vms.h, s-hpux.h: Definitions of BAUD_CONVERT.
+
+        * editfns.c (Fsubst_char_in_region):
+        Call modify_buffer before changing it, and pass entire region.
+        If NOUNDO is set, un-increment bf_modified after that.
+
+1987-03-07  Richard M. Stallman  (rms at prep)
+
+        * lisp.h: #ifndef the definitions of XUINT, XSET, XMARKBIT, etc.
+        Make them all use XUINT when they want to extract the unsigned value.
+
+1987-03-05  Richard M. Stallman  (rms at prep)
+
+        * term.c (write_standout_marker): If "xs" present and sg#0,
+        don't write standout-off markers.

+        * xmenu.c: Include signal.h before xterm.h.
+
+        * sysdep.c (reset_sys_modes): Do fsync (on bsd4.2 or 4.3)

+        * m-sun2.h: Likewise.

+        * process.c: Replace BSD conditionals with HAVE_SOCKETS for tcp stuff.
+        Give NETCONN_P a default definition if not HAVE_SOCKETS.
+        Don't defsubr open_network_stream if not HAVE_SOCKETS.
+
+        * s-*.h: Define HAVE_SOCKETS, or add place holder.

+        * ymakefile (LIBX): add -lXMenu.
+
+1987-03-03  Richard M. Stallman  (rms at prep)
+
+        * fileio.c (Fwrite_region): Really put the `fstat' after
+        the `fsync', trying to solve spurious "file has changed" warnings.
+        This reverses a change made on Jan 28 which was described then
+        as putting the `fstat' after the `fsync' but which in fact
+        was exactly the opposite.  The truth is that anciently the
+        `fstat' was after, and on Jan 28 it was moved before.
+        The change on Jan 28 was to fix some sort of RFS problem.
+        I don't know whether the change itself or just its description
+        was incorrect.
+
+        * Version 18.38 released.
+
+1987-02-28  Chris Hanson  (cph at prep)
+
+        * fileio.c: Added `sysnetunam' function for controlling remote

+
+1987-02-28  Richard M. Stallman  (rms at prep)
+
+        * xdisp.c (display_text_line): Typo in line that fixes tab_width.
+
+1987-02-27  Richard M. Stallman  (rms at prep)
+
+        * dispnew.c (Fopen_termscript): `report_file_error'
+        requires list as 2nd arg.
+
+1987-02-26  Richard M. Stallman  (rms at prep)
+
+        * xmenu.c: New file defining Fx_popup_menu.
+        * emacs.c (main): Call syms_of_xmenu.
+
+        * buffer.c (Fother_buffer): Condition for assigning to
+        `notsogood' was backwards (should be if null).
+
+1987-02-23  Richard M. Stallman  (rms at prep)
+
+        * keymap.c (access_keymap): No longer check lower case
+        equivalent of an upper case letter that is undefined.
+
+        * keyboard.c (read_key_sequence): If an upper case letter
+        is undefined, and corresponding lower case letter is defined,
+        use the lower case letter instead.
+
+        * emacs.c: Delete all ALLIANT conditionals that used to
+        save and restore _curbrk.  Special code in crt0.c now
+        handles this.
+
+        * crt0.c [ISI68K]: Assembler code to put a .word 0 after _start.
+        Include the dummy arg `ignore' in start1.
+
+        * crt0.c [orion/pyramid/celerity]: ALLIANT now uses this case,
+        but with some special code to hack _curbrk on first startup.
+
+        * m-alliant2.h: File deleted.  Use m-alliant.h for version 2.
+        * m-alliant1.h: Don't look for ALLIANT2 to be defined.
+        Now ALLIANT1 is defined for version 1 and not for version 2.
+        Define NO_ARG_ARRAY only for version 1.
+        Define START_FILES so GNU crt0.c gets used.
+        Remove definition of TEXT_START (safe since GNU crt0.c is used).
+        Add to ADJUST_EXEC_HEADER something to set unexec_text_start.
+
+1987-02-22  Richard M. Stallman  (rms at prep)
+
+        * dispnew.c (Fopen_termscript):  Close existing termscript

+        * window.c (set-window-buffer): typo "set-widow-buffer".
+
+1987-02-19  Richard Mlynarik  (mly at prep)
+
+        * lisp.h:
+        Add type Lisp_Window_Configuration, delete Lisp_Temp_Vector.
+        A window configuration is a Lisp_Vector-like object.
+        Add decls for F{set,current}_window_configuration.
+
+        * window.c (F{set,current}_window_configuration):
+        New lisp-callable functions which do the guts of
+        Fsave_window_excursion.
+
+        Also fixed a bug in which point was not being restored in
+        buffer currrent at end of save-window-excursion and that buffer
+        was not current when the config was recorded (It is supposed
+        to not be restored if it was current at the start)
+
+        * alloc.c (mark_object):
+        Add case for Lisp_Window_Configuration; remove code for
+        Lisp_Temp_vector.
+
+        * window.c, window.h:
+        Rename Fshow_buffer Fset_window_buffer (which was previously the
+        synonym in subr.el)
+
+        * keyboard.c, minibuf.c: Window configuration caller changes.
+
+        * print.c (print):
+        Understand Lisp_Window_Configuration's.
+        Print a disturbing message if encounter an illegal dtp --
+        perhaps this should core-dump?
+
+1987-02-17  Richard Mlynarik  (mly at prep)
+
+        * dired.c (Ffile_attributes):
+        Use make_number.  (XINT doesn't work on LHS of assignment)
+
+1987-02-17  Richard M. Stallman  (rms at prep)
+
+        * doc.c (get_doc_string, Fsnarf_documentation):
+        In vms4.4, avoid system bug by using sys_translate_unix
+        to translate filename to VMS format before opening.
+
+1987-02-16  Richard M. Stallman  (rms at prep)
+
+        * crt0.c: Don't define `environ' if DONT_NEED_ENVIRON is defined.
+
+        * m-elxsi.h: Define DONT_NEED_ENVIRON
+        Define C_DEBUG_SWITCH as -O since there is no debugger.
+        Don't define VIRT_ADDR_VARIES.
+
+        * xdisp.c (display_mode_element): Handle SWITCH_ENUM_BUG.
+
+        * sysdep.c (reset_sys_modes): Loop on TCSETAW
+        until it does not get EINTR.

+
+1987-02-13  Richard M. Stallman  (rms at prep)
+
+        * process.c: TCP connection feature from markl@jhereg.lcs.mit.edu.
+        Uses a process-object to represent a connection.
+        childp field is now Qt for a real subprocess,
+        or a hostname string for a tcp connection.
+        NETCONN_P checks this.
+        Status strings "open" and "closed" replace "run" and "exit"
+        for tcp connections only.  New function Fopen_network_stream.
+
+        * dired.c (Ffile_attributes): Use XINT to store the inode #.
+        It can be out of range for integers.
+
+1987-02-12  Richard M. Stallman  (rms at prep)
+
+        * xdisp.c (try_window): Fix paren errer in checking hpos
+        against hscroll.  This caused window_end_pos to be wrong
+        when there was hscroll.
+
+        * xdisp.c (display_text_line): Move code that inserts `$'
+        at bol for hscroll, so that its alteration of p1 does not
+        interfere with setting point_hpos.
+        Use lastpos instead of pos in that code.
+        Make lastpos be accurate in all cases including when there
+        is truncation.
+
+        * xdisp.c (display_string): mincol==-1 means no minimum.
+        * xdisp.c (display_text_line): Use -1 for mincol of minibuf promp.

+
+        * xfns.c (Fx_get_default):  Add (unsigned char *) cast.
+
+        * window.c: typo.
+
+1987-02-09  Richard M. Stallman  (rms at prep)
+
+        * process.c (change_msgs): Save/restore selected buffer
+        only over simple insertions, and over one such at a time.
+        Don't save it across sentinel invocations.
+
+1987-02-08  Richard M. Stallman  (rms at prep)
+
+        * tparam.c (tparam): Supply code for NO_ARG_ARRAY case.
+
+        * window.c, minibuf.c, window.h: Rename minibuf_scroll_window to
+        Vminibuf_scroll_window.  Make it a Lisp variable.
+        * window.c (Fscroll_other_window): Validate
+        Vminibuf_scroll_window since user could store a non-window there.
+
+        * window.c (temp_output_buffer_show):
+        Call Vtemp_output_buffer_show_hook to do the work, if not nil.
+
+        * window.c (Fminibuffer_window): New function.
+
+        * print.c (print, syms_of_print): If print_escape_newlines
+        is nonzero, print newlines in strings as \n.
+
+        * minibuf.c (read_minibuf): Reduce arg to get_minibuf by 1.
+        Thus, use *Minibuf-0* for outer-level minibuffers.
+
+        * keyboard.c (command_loop_1): Pass 2nd arg to Fsit_for.
+        * minibuf.c (temp_minibuf_message): Likewise.
+
+        * dispnew.c (Fsit_for): 2nd arg non-nil means don't redisplay.
+
+        * s-vms.h: Don't define VMS4_0, VMS4_2 or VMS4_4.
+        * s-vms4-[024].h: New files that include s-vms.h and also
+        define VMS4_0 or VMS4_2 or VMS4_4.
+
+        * vmspaths.h: Remove `/emacs' from all paths, to go with a change
+        in emacs.com that includes that path segment in emacs_library.
+
+        * term.c (term_init): Different message on VMS for invalid termtype.
+
+        * alloc.c (Fgarbage_collect): After GC, clear marks

+
+1987-02-07  Richard M. Stallman  (rms at prep)
+
+        * window.c (Fnext_window): Restore old meaning of t as 2nd arg:
+        count minibuffer window even if not active.
+        Non-t-non-nil as 2nd arg means never count minibuffer window.
+
+        * window.c (window_loop): Rewrite to work the old way.
+        The new way did not work when deleting windows.
+
+1987-02-05  Richard M. Stallman  (rms at prep)
+
+        * m-sequent.h: Undef old definition of KERNEL_FILE so no warning.
+
+        * process.c (read_process_output): Don't restore selected buffer
+        after filter; sometimes setting buffer is useful in filter functions.

+        * window.c (window_loop): Rewrite not to pass t as 2nd arg
+        to Fnext_window by starting loop from the window after
+        the minibuffer.  This was sole use of the feature.
+
+        * window.c (Fnext_window): Change meaning of t as 2nd arg.
+        It now means to ignore the minibuffer even if it's active.
+

+
+        * cmds.c (Fforward_line): Correct the returned value.

+
+        * unexec.c (make_hdr): typo `bas_start'.
+
+        * sysdep.c: Declare errno explicitly since errno.h may fail to.
+
+        * fileio.c (Fwrite_region): Move the fstat after the fsync.
+        [Note: the above sentence was incorrect; actually the fstat
+        had been after and was moved *before* the fsync. -- RMS, Mar 3.]
+        Avoids RFS lossage with fsync (maybe).
+
+        * s-rtu.h: Define NLIST_STRUCT and LDAV_SYMBOL.
+        * m-masscomp.h: Check machine type to choose between C_ALLOCA

+1987-01-24  Richard M. Stallman  (rms at prep)
+
+        * unexec.c (make_hdr): New var `bss_end' holds end-of-bss address.
+        This simplifies computation of bss size while keeping it from
+        being negative.
+
+1987-01-23  Richard Mlynarik  (mly at prep)
+
+        * fileio.c (Fexpand_file_name):
+        Have to do checks for "//" "/~" etc even if filename is
+        non-absolute, otherwise things like "~user1/~user2" aren't
+        expanded correctly (was getting "/u/user1/~user2" instead of
+        "/u/user2")
+
+        * doc.c (Fsubstitute_command_keys): Doc fix.
+
+        * m-stride.h: Fixes from bruce@stride.com

+        of evaluated arguments, across the loop that evals them,
+        always set gcproN.nvars to the number of args
+        evalled so far, since the rest of the vector elements
+        are still garbage.
+
+1987-01-21  Richard M. Stallman  (rms at prep)
+
+        * Version 18.36 released.
+
+1987-01-21  Richard M. Stallman  (rms at prep)
+
+        * term.c (write_chars): If we find N identical chars
+        and that is too few for a Repeat operation,

+
+        * dispnew.c (update_line): Fill old line with spaces to
+        screen_width - 1 if it is highlighted (just like new line).

+1987-01-12  Richard Mlynarik  (mly at prep)
+
+        * lread.c (Fload, load_unwind):
+        load_in_progress must be a counter, not a flag since `load' may be

+        * emacs.c (main):
+        Dike out the code which hacked the "-nx" option as synonymous with
+        "-nw" if HAVE_X_WINDOWS -- this code was never distributed

+1987-01-08  Richard M. Stallman  (rms at prep)
+
+        * search.c (Freplace_match): Change declaration `char' to `int'.

+        
+        In DoDsp, rearrange the tests to see whether to use cached

+        Fix some bugs in which cursX and cursY might not be updated

+
+        * editfns.c: Add register declarations and a few vars for cses.

+
+1986-12-16  Richard M. Stallman  (rms at prep)
+
+        * alloc.c: New garbage collection technique for strings.
+
+        Strings that have string blocks individually allocated
+        are called "large strings".  Other strings are called "small".
+
+        The string blocks for small strings are now chained both ways and
+        there is a pointer to the oldest one of them in `first_string_block'.
+        The string blocks for large strings are chained only from the
+        latest to the oldest, and the latest is in `large_string_blocks'.
+
+        Garbage collection starts by setting MARKBIT in the `size' of
+        each large string.  This allows mark_object to distinguish them.
+        MARKBIT in string sizes is cleared by gc_sweep.
+
+        Large strings are freed individually by GC, like vectors.
+        Those in use are marked with ARRAY_MARK_FLAG in the `size' field.
+
+        Small strings are relocated, compressing them within their
+        string blocks.  
+        mark_object puts all slots that point at a string onto a chain
+        which runs from the string's `size' field, through all the slots
+        that used to point at the string.  The end of the chain is shown
+        by a number that is small enough to be a small string's length.
+
+        This new technique avoids calling malloc during GC.  Thus, there
+        is no danger of fatal error on exhausting memory.  Also, space
+        needed for strings is cut in half.
+
+        The new technique introduces a potential for bugs, however.
+        If any slot is marked twice--for example, if it is GCPRO'd
+        twice by different functions--and it contains a string,
+        the ref chain of the string may become garbled.  Sometimes
+        it will still work!  This is because a slot that's part of a
+        string's ref chain will look like a Lisp_Int if the next thing
+        in the chain is malloc'd memory.  But this will not win if the
+        next thing in the chain is a stack slot, or if malloc'd data
+        lives high up in memory.
+
+        To avoid this problem, MARKBIT is used in stack slots
+        to prevent double marking.
+
+        * bytecode.c (Fbytecode): Adjustment of gcpro1.nvars before
+        call to Ffuncall was off by one.
+
+        * alloc.c (make_uninit_string): make_zero_string renamed as this
+        and no longer zeros the contents.
+        * alloc.c (Fmake_string): initialize string contents.
+
+        * alloc.c (struct string_block): Now chained both ways thru
+        `next' and `prev' fields.  `first_string_block' exists.
+        Strings with individual string blocks are now called "large"
+        and these string blocks go in a separate chain which starts
+        from `large_string_blocks' and runs via `prev' fields only.
+
+        * alloc.c: Stop using clear_marks.  Make gc_sweep clear
+        the marks on all live objects.
+        
+        * alloc.c (malloc_warning, Fgarbage_collect): Eliminate mechanism
+        that defers malloc warnings during GC, since GC no longer calls
+        malloc.
+
+        * fns.c: Fding requires an arg; pass Qnil.
+
+        * m-alliant.h: define TEXT_START as 0x1000.
+        Don't define LIBS_STANDARD; the default (sharable) library
+        is said to work now.
+
+        * alloc.c (mark_object): Now pass address of slot being marked.
+        mark_object itself can alter the slot when necessary.
+        It now returns no value.  All callers changed to pass the address.
+
+        mark_object can now ignore the mark bit if it's set in the slot.
+        Callers need no longer make a copy in which mark bit is clear.
+        mark_object can clear the mark bit so these callers must still
+        set the mark bit again after calling mark_object on such slots.
+
+1986-12-15  Richard M. Stallman  (rms at prep)
+
+        * process.c (create_process): TIOCNOTTY needs no 3rd arg after all.

+        * search.c (search_buffer): In inner loop of BM search,
+        decide dynamically whether signed or unsigned comparison
+        of p_limit vs cursor will give the right results
+        and use the kind that will work.

+
+        * process.c (read_process_output): Read only one buffer worth

+        as local map when calling Fwhere_is_internal.
+
+        * keymap.c (Fwhere_is_internal, where_is_in_buffer):
+        Combine the two functions.  This adds two arguments to
+        Fwhere_is_internal: KEYMAP and FIRSTONLY.
+        To get the old behavior, KEYMAP must be (current-local-map).
+        Therefore, KEYMAP is a mandatory operand for Lisp callers.
+
+        * keymap.c (Fwhere_is): Pass new args to Fwhere_is_internal.
+        * keymap.c (apropos1): Call Fwhere_is_internal instead of
+        where_is_in_buffer.
+
+        * search.c (Freplace_match): Check type of first arg.
+
+        * abbrev.c (Fexpand_abbrev): For abbrev with hook,
+        run the hook in addition to (and following) insertion
+        of the expansion in the usual way.
+
+        * editfns.c (Fformat): [MLY]
+        Compute number of args needed by format string; then
+        convert args from Lisp_Object to int or char *, defaulting
+        any not specified.
+
+        Don't GCPRO; should not be needed since eval is not called.
+
+        * editfns.c (format1): Args are ints or char *'s,
+        not Lisp_Objects.  Call them ints.
+
+1986-12-04  Richard Mlynarik  (mly at prep)
+
+        * xfns.c (Fx_debug):
+        Return Lisp_Object
+
+1986-12-01  Richard Mlynarik  (mly at prep)
+
+        * xfns.c (Fx_set_font):
+        Don't die if font is ""  (I believe this to be an X bug)
+        Also, add interactive specs for Fx_set_(internal_)border_width.
+
+        * lread.c (oblookup):
+        Don't core-dump if data in obarray is invalid
+
+1986-12-01  Richard M. Stallman  (rms at prep)
+
+        * m-att3b.h: on 3b2, 3b5 and 3b15, #define C_OPTIMIZE_SWITCH null
+        since -O triggers compiler bug affecting push_key_description.
+
+1986-11-28  Richard Mlynarik  (mly at prep)
+
+        * keyboard.c (read_key_sequence):
+        Delay setting up the local vars pointing to keymaps until a
+        character has been read.  This is in order that a change of keymap
+        `behind our back' (eg due to a subprocesses action) will be seen.
+
+        * xterm.c:
+        Typo.
+
+1986-11-26  Richard M. Stallman  (rms at prep)
+
+        * sysdep.c (get_system_name):
+         Eliminate internal static var in USG case.
+
+        * lisp.h: New case testing and conversion macros
+        UPPERCASEP, LOWERCASEP, NOCASEP, UPCASE, DOWNCASE.
+        They all work from downcase_table.
+
+        * casefiddle.c (casify_object, casify_region):
+        Use those macros.  Create an enum type for the flags
+        and change the flag names to avoid conflict with the macros.
+
+        * abbrev.c (Fexpand_abbrev): Use those macros.
+        * editfns.c (init_editfns):
+        * fns.c (y-or-n-p):
+        * keymap.c (access_keymap):
+        * fileio.c (report_file_error):
+        * process.c (change_msgs):
+
+        * search.c (Freplace_match): Use upcase_initials_region
+        insead of duplicating it.
+
+        * keyboard.c (Frecursive_edit): If not the top-level edit,
+        specbind standard-output and standard-input to t.
+        * keyboard.c (command_loop_1): Don't set those two vars.
+        This avoids clobbering them permanently when minibuffer is used.
+
+1986-11-25  Richard M. Stallman  (rms at prep)
+
+        * callproc.c (child_setup): New arg `envlen' is length
+        of the list Vprocess_extra_environment.
+        This list's elements (strings) are put at the front of
+        the environment for the other program.
+
+        * callproc.c (Fcall_process): Some rearrangement of
+        local variables for more register decls.  Compute
+        and pass `envlen' arg to child_setup.
+
+        * process.c (create_process):  Compute and pass `envlen' arg
+        to child_setup.
+
+        * xterm.c (x_term_init): Don't call XPopUpWindow at all.
+        Leave it for the term-setup-hook (see lisp/term/x-win.el).
+
+        * keyboard.c (syms_of_keyboard):
+        Delete defsubr for usg-suspend-emacs.
+
+        * fns.c, m-masscomp.h: Rename MASSCOMP_REGISTER_BUG
+        to MASSC_REGISTER_BUG to avoid shortnames confusion on V.0.
+
+        * dispnew.c (direct_output_for_{self_insert,forward_char}):
+        These functions now return 0 if did nothing or 1 if did display.
+        * keyboard.c (command_loop_1): Notice the returned values.
+
+        * window.c (change_window_height):
+        Add new variable delta1 so no need to use delta
+        for two different things.
+        Making window bigger to equal its parent's size used to crash.
+        Fix it by different way of computing delta1 in that case.
+        Move some variable decls to inner blocks and add "register".
+
+1986-11-24  Richard M. Stallman  (rms at prep)
+
+        * buffer.h: `modtime' field = 0 now means no info on visited file.
+        Nonexistent visited file now represented by -1.
+
+        * fileio.c (Fverify_visited_file_modtime):
+        Adjust for changed meaning of `modtime'.
+
+        * fileio.c (Finsert_file_contents):
+        If visiting and file doesn't exist, finish visiting (updating
+        various buffer slots) before getting error, and set modtime to -1.
+
+        * bytecode.c (Fbytecode): Rarrange all the Bvarref cases to
+        share most of the code.  Likewise for Bvarset, Bvarbind
+        and Bunbind cases.  Makes it smaller and makes all
+        Bvarrefs use the fast inline code.
+
+        * keymap.c (Fdefine_key, Flookup_key):
+        Regard chars 0200 and up as equivalent to 2 char sequences
+        starting with meta_prefix_char.
+
+        * search.c (search_buffer and callers):
+        Complete rewrite from king@kestrel using simplified Boyer-Moore
+        algorithm.  Meaning of returned value changed.
+        * search.c (bcmp_buffer_translated): No longer used; deleted.
+
+        * search.c (ScanBf, scan_buffer): complete rewrite of ScanBf
+        and nearly all is now in scan_buffer, a new function.
+        * cmds.c (Fforward_line): Complete rewrite; now calls scan_buffer.
+
+        * search.c (Fscan_buffer): Delete this.
+        * bytecode.c (Fbytecode): Just get error if Bscan_buffer is used.
+
+        * ymakefile: Rename TEXT_START_ADDR to LD_TEXT_START_ADDR
+        to avoid shortname trouble (ymakefile is processed thru
+        the system's cpp).
+
+        * sysdep.c (init_sys_modes): Change #ifdef USG to #ifdef _IOFBF
+        around the call to setvbuf.
+
+        * sysdep.c (bcopy): declare it to return int
+        so that a forward declaration is not needed
+        so there is no problem defining it as a macro.
+
+        * fileio.c (Fwrite_region): Don't try fsync on 4.1bsd.
+
+1986-11-23  Richard M. Stallman  (rms at prep)
+
+        * eval.c (record_unwind_protect, specbind, unbind_to, Funbind_protect):
+        struct specbind now has a new slot `func'.  An internal
+        unwind-protect stores the C function address there; else it's 0.
+        Lisp_Internal_Function data type no longer used.
+        Result is no more dependency on where in the address space
+        function addresses are found.
+
+        * xterm.c (x_term_init): Better message if server does not
+        respond.
+
+        * version 18.31 released.
+
+        * xterm.c, xfns.c (Vxterm1): Lisp var `xterm' now points at
+        Vxterm1, which is initialized like Vxterm but never examined.
+
+        * xterm.c (XTread_socket): Use C-x C-@ to indicate mouse click.
+
+1986-11-22  Richard M. Stallman  (rms at prep)
+
+        * bytecode.c (Fbytecode): Turn on immediate_quit for Bnth loop.
+
+        * keymap.c (Fcurrent_global_map): New function
+        that returns the current global map.
+
+1986-11-21  Richard M. Stallman  (rms at prep)
+
+        * emacs.c (main, Fdump_emacs): [ALLIANT] save _curbrk
+        before dumping and restore when starting dumped Emacs.
+
+        * process.c (wait_reading_process_input):
+        [ALLIANT] if select returns with EFAULT, just set Available = 0.
+        [always] copy errno right after the select and check the copy
+        in case another system call could alter it in between.
+
+        * m-alliant.h, m-mg1.h: New machines supported.
+
+        * ymakefile: Make START_FILES a preprocesser variable
+        and don't change it if already defined.
+        * m-gould.h: Move special gould value of START_FILES here.
+
+        * fileio.c (syms_of_fileio): Define variable vms-stmlf-recfm.
+        * sysdep.c (sys_creat): If vms_stmlf_recfm is nonzero,
+        create new files with rfm=stmlf.
+
+1986-11-20  Richard M. Stallman  (rms at prep)
+
+        * eval.c (unbind_catch): Don't ref thru handlerlist if null.
+
+        * keyboard.c (Fusg_suspend_emacs): Delete this.
+        * sysdep.c (sys_suspend): Put in USG_JOBCTRL
+        method of suspending with ptrace.
+
+1986-11-19  Richard M. Stallman  (rms at prep)
+
+        * xterm.c (x_term_init): Delete attempt to set up
+        a handler for SIGIO.  This was normally overridden in
+        init_keyboard so it didn't matter; but this handler
+        is invalid, so it crashed if it ever did get called.
+
+        * indent.c (compute_motion): Fix screwy #if celerity || ATT3B
+        which is invalid.
+
+1986-11-18  Richard M. Stallman  (rms at prep)
+
+        * keyboard.c (command_loop_1):
+        Must check to reselect buffer and flush minibuf message
+        before trying fast_read_single_key.  Else have lossage
+        typing printing chars when minibuf message is displayed.
+
+        * keyboard.c (Fsuspend_emacs):
+        Execute suspend-resume-hook value on resumption.
+
+        * lisp.h: Make initialized global.
+        * data.c (init_data): Undo last change; not needed now.
+
+1986-11-18  Richard Mlynarik  (mly at prep)
+
+        * emacs.c (main):
+        Giving `inhibit_x_windows' an initialisation loses;
+        do it explicitly.
+
+        * xfns.c (Fx_rubber_band):
+        Make interactive.
+
+1986-11-18  Richard M. Stallman  (rms at prep)
+
+        * dispnew.c (window_change_signal):
+        New function to handle SIGWINCH, defined only if SIGWINCH is.
+        Turned on in init_display if CANNOT_DUMP or if initialized.
+
+        * data.c (init_data), editfns.c (init_editfns):
+        Test initialized, not Vpurify_flag.  Use explicit
+        conditionals to avoid the test when CANNOT_DUMP.
+
+1986-11-17  Richard M. Stallman  (rms at prep)
+
+        * buffer.c (Ferase_buffer): Zero the buffer's save_length.
+        Future text after erase is unrelated to past text
+        so should not suspend auto saving if future text is smaller.
+
+        * buffer.c (init_buffer_once):
+        Was passing entire structure to bzero; now pass address.
+
+        * fns.c: Prevent warning in 4.3 where param.h does #define BSD
+
+1986-11-16  Richard M. Stallman  (rms at prep)
+
+        * dispnew.c (init_display): Set window-system to symbol x, not "X".
+        * dispnew.c (syms_of_dispnew): Initialize window-system to nil.
+
+        * xfns.c (grey_p): Insert missing commas.
+        * emacs.c (main): Fix typo "ihhibit_x_windows".
+
+        * xterm.c (x_term_init): Delay calling XPopUpWindow
+        till after Vxterm is set.  Also must include lisp.h.
+        Also always set Vxterm if CANNOT_DUMP.
+
+        * xfns.c, xterm.c: Include signal.h before xterm.h
+        because on 4.3 both of them define sigmask
+        and only xterm.h considers the case that it is already defined.
+
+        * buffer.h: Add BufferSafeCeiling and BufferSafeFloor.
+
+        * process.c (Fprocess_send_eof):
+        Now has conditional on DID_REMOTE, which is defined
+        if TIOCREMOTE is actually used.
+
+1986-11-15  Richard M. Stallman  (rms at prep)
+
+        * Emacs version 18.30 *
+
+        * xdisp.c (display_string):
+        Change minwidth and maxwidth args to mincol and maxcol:
+        minimum and maximum absolute hpos to end at.
+        Change all callers (all in xdisp).
+
+        * xdisp.c (display_mode_element)
+        Similar change of minwidth and maxwidth args.
+        This permits considerable internal simplification
+        and deletion of the function display_mode_element_1.
+
+        * xdisp.c (decode_mode_spec): Flush unused arg minwidth.
+        Change call (in display_mode_element).
+
+1986-11-14  Richard M. Stallman  (rms at prep)
+
+        * process.c (create_process): Don't get a pty
+        if the new variable Vprocess_connection_type is not t.
+        This is the Lisp variable process-connection-type.
+
+1986-11-13  Richard M. Stallman  (rms at prep)
+
+        * crt0.c: Rename GLOBAL_START_{DOT,NO_DOT}
+        to {DOT,NODOT}_GLOBAL_START to avoid shortnames trouble.
+        * m-vax.h, m-tahoe.h, m-sequent.h: same change.
+
+        * m-att3b.h: Turn off #define VIRT_ADDR_VARIES
+        (kk says no need for it).
+
+        * keyboard.c (Fcommand_execute):
+        Zero debug_on_next_call before running the command.
+
+1986-11-12  Richard Mlynarik  (mly at prep)
+
+        * data.c (Fsequencep):
+        (sequencep nil) => t
+
+        * xdisp.c (display_string):
+        Put a "|" at end of mode-lines of partial-width windows.
+
+        * xdisp.c (various):
+        mode-line-format %259 means to pad field to 259, but not to
+        truncate it.
+        (259 . <format>) also means to pad.
+        (-259 . <format>) means to truncate to 259, but not to pad.
+        [So (-259 . (259 . x)) means to format x -exactly- 259 chars wide.]
+
+        * dispnew.c (Fding):
+        Do not terminate macro-definition if given an argument
+        (This is so things like asynchronous process notifications
+        can beep but not screw)
+
+1986-11-10  Richard M. Stallman  (rms at prep)
+
+        * fileio.c (Fset_file_modes): [APOLLO] must reset
+        modtime after changing the modes.
+
+1986-11-10  Richard Mlynarik  (mly at prep)
+
+        * buffer.c (init_buffer_once):
+        There is no lisp variable corresponding to buffer-name
+
+1986-11-10  Richard M. Stallman  (rms at prep)
+
+        * xdisp.c (display_string): Measure new line length
+        from start of line body.
+
+1986-11-09  Richard M. Stallman  (rms at prep)
+
+        * lread.c (oblookup, map_obarray):
+        Do not use XFASTINT on `next' fields of symbols.
+        Fix incorrect sense of test for end of bucket.
+
+        * filelock.c (current_file_owner):
+        Fix incorrect sense of test with `kill'
+        for death of previous locker.
+
+        * keyboard.c (get_char):
+        Arg of -1 now means don't do redisplay.
+        Rearrange conditionals so detect_input_pending is not called
+        in certain cases.
+
+        * keyboard.c (read_key_sequence):
+        New arg nodisplay, nonzero means pass -1 to 1st call to get_char.
+
+        * keyboard.c (command_loop_1):
+        After a command that does direct screen updating,
+        if buffer_shared is not more than 1,
+        pass 1 for nodisplay to read_key_sequence.
+
+        * minibuf.c (Fminibuffer_depth): New function returns
+        value of MinibufDepth as a Lisp Int.
+
+        * dired.c (Ffile_attributes): Return inode # as element 10.
+
+        * dispnew.c (update_line):
+        Fix bug that noop'd the attempt to let new explicit spaces
+        match the implicit space past end of old line.
+        Also do not ignore trailing spaces in a highlighted line;
+        instead, give it more trailing spaces so it reaches the margin.
+
+1986-11-08  Richard M. Stallman  (rms at prep)
+
+        * data.c (init_data): Don't call signal if purifying.
+        * ymakefile: Stop using gould-sigvec.s.
+        No longer needed now that signal really isn't called.
+        * unexec.c: Eliminate gould-specific code to
+        reinitialize gould-sigvec.s.
+
+1986-11-07  Richard M. Stallman  (rms at prep)
+
+        * m-vax.h: Turn off NO_REMAP.
+
+        * sysdep.c (end_of_{data,text}): Omit them if CANNOT_DUMP.
+
+        * fileio.c (Fwrite_region): APOLLO is now like VMS
+        in doing the stat after the close.
+
+        * emacs.c (main): If APOLLO, don't call malloc_init.
+        We use the system's malloc on the Apollo.
+
+        * editfns.c (init_editfns):
+        If CANNOT_DUMP, do all the work, regardless of Vpurify_flag.
+
+        * alloc.c (mark_object): If not SWITCH_ENUM_BUG
+        don't cast the switch quantity to int.
+
+        * process.c (pty): [HPUX] Do TIOCREMOTE.
+
+        * unexec.c (makehdr): Code to adjust, default and validate
+        data_start and bss_start now common to COFF and non-COFF cases.
+
+        * unexec.c (makehdr): Param SEGMENT_MASK controls rounding of
+        memory-address of text-data boundary (default is pagemask).
+        [COFF only] SECTION_ALIGNMENT controls rounding of file addresses
+        of section beginnings; default is no rounding.
+        [non-COFF] ADJUST_EXEC_HEADER is hook to be executed
+        before filling in a_text, etc. of the header.
+
+        With these parameters, all known machines can be handled
+        with no special conditionals.
+
+        * m-sun1.h, m-sun2.h, m-isi-ov.h: Define SEGMENT_MASK.
+        * m-stride.h, m-nu.h, s-umax.h: Define SECTION_ALIGNMENT.

+        * m-gould.h: Define A_TEXT_OFFSET = sizeof (hdr)
+
+        * unexec.c (makehdr): Remove ibmrt conditionals
+        that adjusted a_text or equivalent, by just copying from
+        the old file when NO_REMAP.
+
+        * unexec.c (makehdr): Zero supplied as entry_address
+        means copy it from the old file.
+        * emacs.c (Fdump_emacs): Pass 0 as entry_address to unexec.
+
+        * unexec.c (copy_text_and_data):
+        Two fixes for A_TEXT_OFFSET case:
+        Don't decrement `end', and remove (unconditionally)
+        the lseek before writing the data segment.
+
+1986-11-06  Richard M. Stallman  (rms at prep)
+
+        * keymap.c (apropos1): Use Fdocumentation_property, not Fget,
+        for doc strings of variables.
+
+1986-11-05  Richard Mlynarik  (mly at prep)
+
+        * m-att3b.h:
+        #define TEXT_START 0
+
+1986-11-05  Richard M. Stallman  (rms at prep)
+
+        * alloc.c (Fcons, Fmake_symbol, Fmake_marker, gc_sweep):
+        The free-list pointers in symbols, conses and markers
+        are now C pointers cast as ints and stored in the XFASTINT.
+        This may make faster code and in any case avoids problems
+        with machines where access with XPNTR relocates the pointer.
+
+        * lread.c (oblookup, map_obarray):
+        Use XFASTINT when comparing a Lisp_Object against zero.
+
+        * minibuf.c (read_minibuf):
+        If noninteractive, print the prompt, since
+        it won't be displayed in the normal way.
+        In any case, pass Fread the string rather than a buffer
+        when reading an s-expression.
+
+        * auxdoc.c, callint.c, syntax.c, ymakefile:
+        Copy fake-DEFUNs from auxdoc.c into comments
+        preceding the real DEFUNs for the same functions.
+        auxdoc.c is no longer in use.
+
+        * fileio.c (Fread_file_name_internal):
+        [VMS only] Return t if file name is null string.
+
+1986-11-04  Richard M. Stallman  (rms at prep)
+
+        * buffer.c (Fget_buffer_create):
+        For default-major-mode = nil case, use fundamental-mode
+        if old buffer's mode name has a non-nil mode-class property.
+        Requires creating Qmode_class to hold the symbol mode-class.
+
+        * s-hpux.h: #undef HAVE_PTYS because of problems with
+        scheme running as an inferior on a pty.
+        jinx@prep requested this.
+
+        * lread.c (check_obarray & its callers): eliminate 2nd arg.
+        Also, don't confuse types int and Lisp_Object.
+        If invalid value matches Vobarray, store a valid Vobarray.
+
+        * editfns.c (Fformat): Don't use an initialization for tem
+        since it is a Lisp_Object and that can be a struct.
+
+        * minibuf.c (Ftry_completion, Fall_completions):
+        Use XFASTINT when testing `bucket' for nonzero or
+        setting it to zero.
+
+        * callint.c (Fcall_interactively): If visargs[i] is nil,
+        don't try to reference it as a string.
+
+        * doc.c (FSnarf_dcumentation):
+        Was assuming exec-path was a string.  Fixed to use
+        exec-directory instead, and to validate its data type first.
+
+1986-11-04  Richard Mlynarik  (mly at prep)
+
+        * m-isi.h => m-isi-ov.h
+
+1986-11-04  Richard M. Stallman  (rms at prep)
+
+        * buffer.c (init_buffer_once):
+        Avoid casts from int to Lisp_Object (which would lose
+        if NO_UNION_TYPE is not defined); use XFASTINT.
+
+1986-11-03  Richard Mlynarik  (mly at prep)
+
+        * xterm.c (stufflines):
+        Initialise signal mask.
+
+        * xterm.h:
+        Add definition of sigmask
+
+1986-11-01  Richard Mlynarik  (mly at prep)
+
+        * m-sun3.h:
+        #undef sun2 ? #define sun3
+
+        * termcap.c:
+        Include Dave Genzel @ Unilogic's VMS termcap stuff.
+
+        * termcap.c:
+        #ifdef emacs ? #include config.h
+
+        * fileio.c, fns.c, m-vax.h:
+        Fixes for VMS cpp. (#undef foo -> #ifdef foo ? #undef foo)
+
+1986-10-31  Richard Mlynarik  (mly at prep)
+
+        * vmsmakefile (new file)
+
+        * crt0.c, unexec.c, m-isi.h (new file):
+        Integrated Solutions 68k port.
+
+1986-10-30  Richard Mlynarik  (mly at prep)
+
+        * m-vax.h (USG-only changes):
+        #define NO_REMAP (I don't understand exactly why one needs to do
+        this -- is there an unexec bug?)
+        #define TEXT_START = 0, since C code can't access `start' symbol.
+
+        * lisp.h, sysdep.c, indent.c, m-att3b.h:
+        USG and att3bxxx changes from karl@ohio-state.arpa
+        Define NO_REMAP, undefine LD_SWITCH_MACHINE
+
+        * buffer.c (Fbuffer_local_variables):
+        Return correct values when buffer is selected-buffer
+
+        * keyboard.c (cmd_error):
+        non-zero exit status on error.
+
+        * filelock.c:
+        Don't get MPV if buffer-file-name isn't a string or nil.
+
+1986-10-29  Richard Mlynarik  (mly at prep)
+
+        * keymap.c (Flookup_key, Fdefine_key):
+        Don't bomb on zero-length strings.
+
+        * filelock.c (Ffile_locked_p):
+        New function.
+
+        * window.c (Fset_window_hscroll):
+        Don't inhibit redisplay optimisations if hscroll is same.
+
+        * ymakefile:
+        rm ../etc/DOC to avoid make-docfile overwriting any files which
+        were linked to it (unix sucks)
+
+1986-10-28  Richard Mlynarik  (mly at prep)
+
+        * vmsmap.c, termcap.c, sysdep.c, config.h-dist:
+        VMS changes from Sasaki
+
+        * termcap.c (tgetent):
+        Make sure `indirect' initialised.
+
+        * xfns.c (grey_p and callers):
+        New function to compensate for ugly chauvinistic American
+        spelling.
+
+        * keymap.c (describe_*):
+        Don't mention keys in global map which are shadowed by
+        local bindings
+
+        * dispnew.c, sysdep.c, dired.c:
+        Eschew ^#if.*defined (for VMS' sake)
+
+        * keymap.c (Fkeymapp, Flookup_key):
+        Add QUIT test.
+
+1986-10-27  Richard Mlynarik  (mly at prep)
+
+        * callproc.c, fileio.c:
+        VMS changes (make environ noshare, don't call fsync)
+
+1986-10-26  Richard Mlynarik  (mly at prep)
+
+        * sysdep.c, unexec.c, ymakefile:
+        Gould changes. (marick%cthulhu@gswd-vms.ARPA)
+
+        * gould-sigvec.s:
+        New file.
+
+        * m-gould.h:
+        New file (for utx/32 2.0 and above)
+        Old file renamed m-ogould.h.  See etc/MACHINES
+        for more information.
+
+        * unexec.c (make_hdr):
+        Typo "#ifdef A_TXT_OFFSET" should be "A_TEXT_OFFSET"    
+
+1986-10-22  Richard Mlynarik  (mly at prep)
+
+        * keyboard.c, keymap.c:
+        Move Fexecute_extended_command from keymap.c to keyboard.c rather
+        than make kludgy static vars global.
+
+        In Fexecute_extended_command record `(this-command-keys)' and
+        `last-command' accurately.
+
+        * emacs.c (main), dispnew.c (init_display):
+        Add -nx flag, meaning to inhibit X windows and just run in the
+        current virtual terminal.  (Perhaps there should be a generic flag
+        to disable any special window-system code)
+        Add Vwindow_system variable.
+
+        * search.c (Fstring_match):
+        Do range-checking on `start' argument.
+
+1986-10-21  Richard Mlynarik  (mly at prep)
+
+        * xterm.c, xfns.c (x_term_init, x_change_display):
+        Share command code, and make that code use
+        {request,unrequest,init}_sigio
+
+        * term.c (init_display):
+        Determine whether we are under X by whether DISPLAY env var is
+        set, not by whether TERM is "xterm"
+
+        * xterm.c (x_term_init):
+        Remove (if (!initialized) ...) test.
+        Set Vxterm directly, rather than calling setxterm (flush latter)
+
+        * lread.c (various):
+        Changes for when can't take XSYMBOL of 0 and to make check_obarray
+        code work correctly.
+
+1986-10-20  Richard Mlynarik  (mly at prep)
+
+        * m-stride.h, process.c, sysdep.c, unexec.c:
+        Stride changes.
+
+1986-10-18  Richard Mlynarik  (mly at prep)
+
+        * buffer.c:
+        Made default-major-mode same as (default-value 'major-mode) to
+        avoid user confusion.
+
+1986-10-17  Richard Mlynarik  (mly at prep)
+
+        * cmd.c, process.c:
+        Doc fixes from sjk 
+
+        * buffer.c (init_buffer_once):
+        Do x = (Lisp_Object) 1 instead of (int) x = 1 for benefit of vms
+        and pyramid compilers.
+
+        * minibuf.c (Ftry_completion):
+        Test (bucket), not (XSYMBOL (bucket)) since Lisp_Objects may not
+        be able to be 0 on some implementations.
+
+        * editfns.c (Fformat):
+        Have to duplicate doprnt's work of decoding the
+        format-string top ensure that don't die on (format "%s" 0)
+        Also, use prin1-to-string to get PR for random objects
+
+        * m-celerity.h:
+        HAVE_ALLOCA
+
+1986-10-16  Richard Mlynarik  (mly at prep)
+
+        * m-att3b.h:
+        New file -- replaces m-3b20.h
+
+        * alloca.c, fileio.c, indent.c, unexec.c, ymakefile:
+        Bugs and fixes for att3b (and usg)
+        Use a global static var rather than a local one
+        to record the last block allocated by alloca.
+
+        * fileio.c (Fverify_visited_file_modtime):
+        If a formerly-nonexistent file has been created since we ``found''
+        it, say there is a discrepancy.
+
+1986-10-14  Richard Mlynarik  (mly at prep)
+
+        * callint.c (Fprefix_numeric_value):
+        Doc typo.
+
+        * malloc.c, regex.c:
+        Nuke "#if defined..." for VMS
+
+1986-10-12  Richard Mlynarik  (mly at prep)
+
+        * xdisp.c (many functions):
+        Rearrange the way in which the mode-line stuff is hacked:
+        in particular, display_string doesn't have a special-case
+        for %-escapes -- this is now all done in display_mode_element.
+        This was necessary to make %M work correctly.
+        Also, fix a few bugs (buffer-name truncation could cause
+        core-dump)
+
+        Dike out global-minor-modes.  This wasn't actually being used by
+        anything (due to a bug) and wasn't even being initialised!
+        minor-mode-alist does what this thought it was doing.
+
+1986-10-11  Richard Mlynarik  (mly at prep)
+
+        * doc.c (FSnarf_documentation):
+        In CANNOT_DUMP case wasn't treating PATH_EXEC as a path --
+        now uses exec-path instead.     
+
+        * lisp.h:
+        Get rid of #if defined... for benefit of vms
+
+1986-10-09  Richard Mlynarik  (mly at prep)
+
+        * abbrev.c (Funexpand_abbrev):
+        Preserve position of point.
+
+1986-10-07  Richard Mlynarik  (mly at prep)
+
+        * s-hpux.h:
+        #define HAVE_PTYS
+
+        * alloca.c:
+        Make some attempt to work in the USG case where "#define static"
+        is done.
+
+        * keyboard.c:
+        #undef FIONREAD in HPUX (seems to be unimplemented or broken)
+        The only reason this ever seemed to work was because of a bug in
+        v17.
+
+        * sysdep.c (child_setup_tty):
+        HPUX was defaulting terminal speed to 300 baud.
+
+        * alloca.s:
+        New hp9000 C function calling sequence.
+
+        * fileio.c (Fexpand_file_name):
+        Fix bug in (expand-file-name ".." "/foo/")
+
+        * callint.c (Fcall_interactively):
+        Remove extreme weirdness of storing (int) "" where a Lisp_Object
+        was expected (in visargs)
+        Slighly more informative error message for bad interactive code
+        letter.
+
+        * abbrev.c (Funexpand_abbrev):
+        Was deleting length of original text rather than length of
+        expanded abbrev.
+
+        * abbrev.c (Fexpand_abbrev):
+        Add an Fundo_boundary so that undo works to unexpand
+        abbrevs.
+
+1986-10-03  Richard M. Stallman  (rms at prep)
+
+        * ymakefile: Make LIBS_STANDARD the last libs loaded.
+
+        * xterm.c: Load sys/types.h explicitly if xterm.h doesn't do it.
+
+        * keyboard.c (interrupt_signal):
+        Delete suprious `)' in HAVE_X_WINDOWS case.
+
+1986-10-03  Richard Mlynarik  (mly at prep)
+
+        * sysdep.c (sys_suspend -- fake suspend case)
+        Missing comment */ terminator
+
+1986-10-02  Richard Mlynarik  (mly at prep)
+
+        * search.c:
+        There may be `holes' in regexp registers after a match: consider
+        matching "z" against "\\(\\(xyzzy\\)\\|\\)\\(z\\)" -- then
+        register 2 is unmatched, whilst registers 0, 1 and 3 have matches.
+        Fix register-hacking code in Flooking_at, search_buffer,
+        Fmatch_data, Fstore_match_data.
+
+        * crt0.c:
+        HP200 floating-point (sigh -- needed for load-average)
+
+        * sysdep.c (HPUX perror):
+        Should be "perror" not "_perror" -- communication foulup, sorry.
+
+1986-10-01  Richard M. Stallman  (rms at prep)
+
+        * marker.c (Fcopy_marker): Was stupidly failing to put
+        the new marker on the buffer's chain.  Fix to go thru Fset_marker.
+        This really does fix the crashes in GC.
+
+        * sysdep.c (for HPUX): Define utimes and _perror as no-ops.
+
+        * marker.c (Fset_marker): If attempt to set marker
+        to point to a dead buffer, set it to point nowhere.
+
+        * buffer.c (Fkill_buffer): Clear out the buffer's markers chain.
+
+        * keyboard.c (interrupt_signal):
+        Turn off the double-C-g feature when running under X windows.
+
+1986-09-29  Richard M. Stallman  (rms at prep)
+
+        * search.c: search_regs elements are now the correct character
+        numbers or string indices.  1 is not added when they are used;
+        instead the values are corrected just after regex library returns.
+        The loops to do this exit at the first -1 (unused register).
+
+        * alloca.s: Convert HP9000 code to new assembler syntax.
+        Rename flag hp9000s200 to hp9000. [mly]
+
+        * crt0.c: Convert HP9000 code to new assembler syntax. [mly]
+
+        * buffer.c (Fdelete_buffer_internal): Unused; deleted.
+
+        * marker.c (unchain_marker):
+        Dump core if first marker on buffers marker list
+        does not have that buffer as its buffer.
+        May help find bug where after GC a buffer's first marker
+        was on the free list.
+
+        * keyboard.c (cmd_error): In -batch, die after error message.
+
+        * bytecode.c (Fbytecode):
+        Open-code Bvarref with one-byte arg.
+
+        * callproc.c (init_callproc): Use only first element of
+        Vexec_path to make Vexec_directory.  [mly]
+
+1986-09-28  Richard M. Stallman  (rms at prep)
+
+        * data.c (Fsymbol_value): use assq_no_quit instead of Fassq.
+        * fns.c (assq_no_quit): Like Fassq but never quits or gets errors.
+
+        * keyboard.c (quit_throw_to_get_char):
+        * eval.c (Fsignal):
+        Call quit_error_check.
+        * dispnew.c (quit_error_check):
+        Dump core if DesiredScreen is not full of zeros.
+        This is to catch the bug wherein DoDsp called from get_char
+        died because DesiredScreen was full of lines already.
+
+1986-09-26  Richard Mlynarik  (mly at prep)
+
+        * regex.c (re_match_2), search.c (various):
+        The registers modified by re_{search,match}{,_2}
+        now have start and end of -1 if that register was
+        not used in the match found.
+        Fmatch_data now returns a list of twice the number of registers
+        -actually- used (including register 0, for the whole match)
+
+        * process.c (Fwaiting_for_user_input_p):
+        New function for use by process-filters and sentinels
+        so they can determine if it might be an appropriate time
+        to try to make some sort of asynchronous notification.
+
+1986-09-26  Richard M. Stallman  (rms at prep)
+
+        * keymap.c (syms_of_keymap): Add missing defsubr
+        for Fdefine_prefix_command,
+
+        * abbrev.c (Fexpand_abbrev): Save original text of the abbrev
+        in Vlast_abbrev_text.
+        * abbrev.c (Funexpand_abbrev): Restore the original text.
+        Thus expand and unexpand preserves case.
+        Also, if there is no abbrev to unexpand, do nothing.
+        * abbrev.c (syms_of_abbrev):
+        Turn Lisp variables last-abbrev and last-abbrev-text back on.
+        * abbrev.c (Flast_abbrev_expansion): Delete this function.
+
+1986-09-25  Richard M. Stallman  (rms at prep)
+
+        * window.c (Fwindow_width): return a value one smaller
+        for partial-width windows that contain a | border.
+
+        * macros.c: Remove Fname_last_kbd_macro (moved to macros.el).
+
+1986-09-25  Richard Mlynarik  (mly at prep)
+
+        * unexec.c:
+        Include a.out.h before getpagesize.h, since EXEC_PAGESIZE
+        may be defined in a.out.h
+
+        * dispnew.c:
+        Only define TIOCOUTQ as TCOUTQ if the latter as defined,
+        so that ifdef conditionals on the former work as expected.
+
+        * sysdep.c (sys_suspend):
+        Needed to include buffer.h for getting cwd when doing a fake suspend.
+          (for system v and other complete losers)
+        Rather than doing that include (which tickled some cretin-compiler
+        bugs) look up bf_cur->default_directory by
+        Fsymbol_value (Qintern ("..."))
+
+1986-09-24  Richard Mlynarik  (mly at prep)
+
+        * editfns.c (Fregion_beginning, Fregion_end):
+        Share common code (this doesn't have to be so fast that the
+        extra function-call could hurt)
+
+        * editfns.c, window.c, callint.c, buffer.c:
+        Don't allow bf_cur->mark to be nil.
+        Instead, to indicate that the mark is not set,
+        make the marker not point at anything.
+        This simplifies life quite a lot.
+
+        Add sanity checking in case user sets mark to point to different
+        buffer (he could do this by side-effecting (marker-mark) stupidly)
+
+        Change definition of marker-mark so that it returns a marker
+        object which doesn't point anywhere when there is no mark,
+        rather than nil.  This is more useful.
+
+        * editfns.c, bytecode.c.
+        Move set-mark, mark to lisp code.
+
+        * editfns.c (Fset_mark)
+        Not interactive.
+
+1986-09-23  Richard M. Stallman  (rms at prep)
+
+        * crt0.c, m-hp9000.h: rename hp9000s200 to hp9000.
+        * m-hp9000.h: New name for m-hp200.h.
+        * unexec.c (for hpux): define MY_ID from HP9000S200_ID
+        if that exists; else use model.h.
+        
+
+1986-09-21  Richard M. Stallman  (rms at prep)
+
+        * search.c (search_buffer): Fix backwards condition
+        in whether the translate table can be ignored.
+
+        * process.c (Fprocess_send_string): Name of function for Lisp
+        had a typo.
+
+        * eval.c: When looping getting the function definitions of
+        symbols, check for quit.
+
+        * lisp.h: Restore old declaration of `getenv'
+        since removing it causes warnings in many places.
+
+        * minibuf.c (scmp): Return correct value.
+
+1986-09-21  Richard Mlynarik  (mly at prep)
+
+        * editfns.c (Finsert_char):
+        New function.  There are a lot of places in lisp code
+        which want to insert multiple copies of a constant char.
+        This is a faster way of doing it, and doesn't cons
+        (unlike (insert (make-string n c)))
+
+1986-09-21  Richard M. Stallman  (rms at prep)
+
+        * process.c (make_process): Code to compute # elts in
+        vector to make a Lisp_Process had several errors:
+        Took size of pointer rather than of struct Lisp_Vector
+        and had wrong sign compensating for first element.
+
+        * fileio.c (directory_file_name): If arg is "/", return "/".
+
+1986-09-20  Richard M. Stallman  (rms at prep)
+
+        * minibuf.c (Fdisplay_completion_list):
+        New Lisp-callable function replaces minibuffer_completion_help_1,
+        with a little new feature: elements of the completion list
+        may be lists of two strings, and if so the two strings
+        are printed in immediate succession.
+
+1986-09-19  Richard Mlynarik  (mly at prep)
+
+        * minibuf.c (scmp and callers)
+        Don't be fazed by '\0' in strings.
+
+        * lisp.h, search.c, minibuf.c
+        Use downcase_table
+
+1986-09-18  Richard Mlynarik  (mly at prep)
+
+        * ymakefile, emacs.c, callproc.c, process.c, fns.c
+        Install MAINTAIN_ENVIRONMENT conditional to call environ.c.
+
+1986-09-16  Richard M. Stallman  (rms at prep)
+
+        * keymap.c (where_is_in_buffer): Fix bug in checking for shadowed
+        keys: do Flookup_key only on local map, and ignore value if
+        it is a number (that means key is locally undefined).
+
+1986-09-15  Richard Mlynarik  (mly at prep)
+
+        * buffer.c (Fbury_buffer)
+        Make this function interactive (bury current buffer)
+        Do error-checking on arg.
+
+1986-09-15  Richard M. Stallman  (rms at prep)
+
+        * emacs.c (main): Eliminate VMS -nl switch.
+        Instead, `-map FILE' says to map data file FILE;
+        no switch means don't map any file.
+        Can call mapin_data directly since exact file name is given.
+
+        * emacs.c (undump_emacs): Delete this.
+
+        * emacs.c (main): Make it work to use more than one of the
+        special switches (-batch, -t, -map).
+
+1986-09-14  Richard M. Stallman  (rms at prep)
+
+        * Renamings for VMS.
+        config.h.dist => config.h-dist
+        paths.h.dist => paths.h-dist
+        [ms]-*.*.h => [ms]-*-*.h
+        s-usg5.2.2.h => s-usg5-2-2.h
+
+        * Some new files for VMS.
+        compile.com, link.com, precomp.com, ccom.com,
+        testemacs.com, build.com are command files.
+        temacs.opt is a linker control file.
+        VMSBUILD gives info on how to use them.
+        README describes what this directory is for.
+
+1986-09-13  Richard M. Stallman  (rms at prep)
+
+        * sysdep.c (reset_sys_modes):
+        Delete never-used VMS & SIGIO conditional.
+        Call reset_sigio just once.  No need to clear FASYNC here
+        now that init_sigio makes sure it is clear in old_fcntl_modes.
+
+        * eval.c (top_level_value, top_level_set):
+        These are new names for Fglobal_value and Fglobal_set,
+        which are no longer callable from Lisp.
+        They are also commented out.
+
+1986-09-12  Richard Mlynarik  (mly at prep)
+
+        * xfns.c (Fx_rebind_key)
+        Fix typo.
+
+        * mocklisp.c:
+        Delete ml-substr.  Move to mlsupport.el
+
+        * buffer.c
+        The real work of setting up mode_line_default is done in
+        loaddefs.el.
+
+        * lread.c, data.c, marker.c, window.c
+        Flush the last callers of defalias.  Flush defalias.
+        (Use fsets in subr.el instead)
+
+1986-09-11  Richard Mlynarik  (mly at prep)
+
+        * emacs.c (main)
+        Under X, accept "-display" switch as synonym for "-d"
+
+        * eval.c (spedcbind)
+        Don't make Lisp_Buffer_Objfwd's buffer-local when just binding.
+        (so now (let ((case-fold-search t))) doesn't force buffer-localness)
+        However, setting a binding will still make it buffer-local.
+        (ie (let ((case-fold-search t)) (setq case-fold-search t))
+         will cause case-fold-search be buffer-local even outside the let)
+
+        * xfns.c
+        Preserve studlycaps: "Gnuemacs" => "GNU Emacs"
+
+        * Various
+        Flush last users of LISTP => CONSP
+
+        * buffer.h
+        Make backed_up a Lisp_Object, since it is one!
+        Make abbrev_table a magic-local-variable.
+
+        * alloc.c (mark_buffer)
+        Simplify, simplify.
+
+        * buffer.h:
+        Reorder elements of struct buffer so that Lisp_Object
+        slots are contiguous from buffer.name through to the
+        end of the buffer.  All slots before buffer.name are
+        not Lisp_Objects (except buffer.markers, which is gc-magic)
+
+        Eliminate useless buffer.number slot.
+
+        * buffer.c (Fbuffer_number):
+        delete. 
+
+1986-09-10  Richard M. Stallman  (rms at prep)
+
+        * process.c (Fsend_{string,region}): rename as Fprocess_send...
+        and change names of Lisp function.  Old names now aliases in subr.el.
+
+1986-09-10  Richard Mlynarik  (mly at prep)
+
+        * buffer.c
+        New struct buffer_local_symbols.
+        staticpro buffer_defaults, buffer_local_symbols.
+
+        * lread.c (defvar_per_buffer)
+        Hack buffer_local_symbols
+
+        * buffer.c (Fbuffer_local_variables)
+        (a) Fcopy_alist so don't return any shared list structure
+        (b) Include names and values of Lisp_Buffer_Objfwd locals.
+
+        * alloc.c (FGarbage_collect):
+        Don't mark buffer_defaults specially, as it is now in staticvec
+
+        * dired.c (Fdirectory_files):
+        Optional third argument match is a regexp specifying
+        to only return files whose names contain a match for that regexp.
+        [eg ``(directory-files "/u2/emacs/" nil "\\`[^#]")'']
+
+1986-09-10  Richard M. Stallman  (rms at prep)
+
+        * alloc.c (Fgarbage_collect): Use open code instead of Fnthcdr
+        to avoid possibility of error.
+
+        * lread.c (Fload, load_unwind): The Lisp_Internal_Stream
+        now points to a word got with xmalloc and that points to the FILE.
+        On Elxsi, the FILE address is not in the part of the address
+        space that Lisp_Object pointers can reach.  New way can't lose.
+
+1986-09-09  Richard M. Stallman  (rms at prep)
+
+        * crt0.c: Add _start for elxsi.
+
+1986-09-07  Richard Mlynarik  (mly at prep)
+
+        * minibuf.c (read_minibuf)
+        gc-protect the saved data!
+          I'm don't know why this doesn't just bind help-form
+          (and current-prefix-arg) esp since there is already an
+           unbind_to which would help us do this.
+           Since I don't know why the `bindings' are done this way,
+           I'm leaving the unwind-protect hair, and adding GCPRO hair.
+
+        * minibuf.c (read_minibuf, read_minibuf_unwind)
+        preserve the value of current-prefix-arg.
+
+        * minibuf.c:
+        Eliminate read_minibuf_string.
+        Move defalias for read-input to subr.el
+
+        * callint.c, fns.c, lisp.h
+        Call read_minibuf instead of read_minibuf_string.
+
+1986-09-04  Richard Mlynarik  (mly at prep)
+
+        * fns.c (Fy_or_n_p, Fyes_or_n_p)
+        Beep if the user types an invalid response.
+
+1986-09-03  Richard M. Stallman  (rms at prep)
+
+        * dispnew.c (update_screen):
+        Take out previous change.
+
+        * xdisp.c (DoDsp): Move call to request_sigio
+        after update: so it cannot be bypassed.
+
+        * sysdep.c (init_sigio): set old_fcntl_flags here
+        only once; don't change it in request_sigio.
+        * sysdep.c ({un,}request_sigio):
+        Set interrupts_deferred while SIGIO is unrequested.
+        Abort if FASYNC is already set when request_sigio is called.
+        * keyboard.c (get_input_pending):
+        Always do FIONREAD if interrupts_deferred.
+
+1986-09-01  Richard M. Stallman  (rms at prep)
+
+        * xterm.c/xfns.c: Many changes from rlk,
+        including using sigblock/sigsetmask to block signals
+        instead of turning handler off and on.
+
+        * dispnew.c (update_screen):
+        If interrupt input, wait while output gets written
+        before returning.  If observed loss of output really is
+        a kernel bug, this may make it stop.
+
+1986-08-31  Richard M. Stallman  (rms at prep)
+
+        * keymap.c (where_is_in_buffer):
+        Use Fequal rather than EQ to test for a match
+        if the object being searched for is a cons cell.
+
+1986-08-30  Richard M. Stallman  (rms at prep)
+
+        * data.c (Fsetq_default): new function.
+
+1986-08-28  Richard M. Stallman  (rms at prep)
+
+        * xdisp.c (display_mode_element):
+        Cons cell whose car is a symbol now means
+        (SYMBOL IF_TRUE_DISPLAY IF_FALSE_DISPLAY)
+        and is equivalent to IF_TRUE_DISPLAY if SYMBOL's value is non-nil
+        or to IF_FALSE_DISPLAY if SYMBOL is unbound or has value nil.
+        * buffer.c (syms_of_buffer): update documentation for that.
+
+1986-08-25  Richard M. Stallman  (rms at prep)
+
+        * fns.c (merge): Swap the arguments to the sort predicate
+        so as to use it to compute <= rather than <.
+        Sort had been anti-stable; now it is stable.
+
+        * editfns.c (Fuser_uid, Fuser_real_uid):
+        New functions that return values of geteuid and getuid system calls.
+
+        * dired.c (Ffile_attributes):  Value has additional element
+        t iff file gid would change if Emacs deletes it and recreates it.
+
+        * xdisp.c (display_mode_element):
+        If element is a list and its car is a list,
+        process all list elements recursively and concatenate them.
+        Makes alists work.
+
+        * xdisp.c (display_mode_string): New element type %n
+        prints ` Narrow' and ` Def' if appropriate.
+        * buffer.c (syms_of_buffer): Fix documentation of mode-line-format.
+
+        * undo.c (Fundo_more):
+        Fix bugs in checking len and pos for being in bounds.
+
+        * eval.c (Fuser_variable_p):
+        If documentation property is a number,
+        negative means it's a user variable.
+        * doc.c (Fdocumentation_property):
+        Use abs value of property as the file position.
+        * doc.c (FSnarf_documentation):
+        For variables, store negative property if string starts with `*'.
+
+        * editfns.c (Finsert_buffer_substring):
+        Implement inserting part of a buffer into itself.
+
+1986-08-24  Richard M. Stallman  (rms at prep)
+
+        * xterm.c, xfns.c, sink.h: Installed latest changes from
+        Athena, and fixed up formatting conventions.
+
+1986-08-23  Richard M. Stallman  (rms at prep)
+
+        * eval.c (unbind_catch): Restore gcprolist from the catchtag.
+
+1986-08-21  Richard M. Stallman  (rms at prep)
+
+        * fileio.c (barf_or_query_if_file_exists):
+        New second arg non-0 says query; do not call Finteractive_p.
+
+        * fileio.c (Frename_file, Fcopy_to_file, Fadd_name_to_file,
+        Fmake_symbolic_link):
+        Interactive spec now says `p' for the third arg.
+        If third arg is number, do call barf_or_query_if_file_exists
+        but pass nonzero second arg in that case.
+
+        * eval.c (Finteractive_p): Skip the innermost frame
+        when examining the stack.  This makes the right thing happen
+        if called from Fbyte_code.
+
+1986-08-21  Richard Mlynarik  (mly at prep)
+
+        * process.c (handle_process_output):
+        do a set-buffer back to original buffer
+        after calling a process' filter function so that
+        all filter functions needn't save-excursion.
+
+        * keymap.c (where_is_in_buffer):
+        Don't blow out if buffer has no local map.
+
+1986-08-21  Richard M. Stallman  (rms at prep)
+
+        * emacs.c (main): Eliminate references to environ.c.
+
+        * callproc.c (Fcall_process): Pass child_setup
+        the standard Unix environment.
+        * process.c (create_process): likewise.
+
+        * bytecode.c (Fbyte_code): At end, abort if specpdl
+        is not back to same level it had on entry.
+
+        * eval.c (unbind_catch):
+        New way to unbind for throw.  Pops catches, handlers
+        and bindings, in one synchronized pass.  Thus, when an
+        unwind-protect is executed, all catches and handlers
+        outside of it are still in effect.
+        Also restore various static variables from the catchtag
+        being unbound.  struct catchtag has two new fields,
+        gcpro and pdlcount.
+
+        * eval.c (Fthrow, Fsignal):  Use unbind_catch before longjmp.
+
+        * eval.c (internal_catch): No need to restore anything
+        from the catchtag after throw, because unbind_catch does it all.
+        Must set up pdlcount and gcpro fields.
+        * eval.c (internal_condition_case, Fcondition_case):
+        Changed like internal_catch.
+        * eval.c (Fcatch): use internal_catch to do the work.
+
+        * eval.c (Fsignal): If no handler applies, try calling
+        the Lisp debugger; if that fails, throw to top-level.
+        Don't call `debugger'.
+
+        * keyboard.c (debugger): Delete this function.
+
+1986-08-20  Richard M. Stallman  (rms at prep)
+
+        * Gap motion can now quit!
+
+        * insdel.c (move_gap): new name for GapTo.  Callers changed.
+
+        * insdel.c (InsCStr):
+        * fileio.c (Finsert_file_contents):
+        Call move_gap before calling record_insert.
+        * insdel.c (del_range):
+        Don't adjust point until after all possible errors detected,
+        which means after gap is moved.
+
+        * insdel.c (gap_right, gap_left):
+        Check every 32000 chars for pending quit.
+        Also speed up char-copy inner loop.
+
+        * lisp.h (QUITP): New macro, nonzero if ought to quit now if poss.
+
+1986-08-20  Richard M. Stallman  (rms at prep)
+
+        * undo.c (Fundo_more):
+        Fix bug that was setting point to `len' field, not `pos' field.
+        Share the error-checking code between all three types of
+        undo record that actually make changes.
+
+        * xdisp.c (display_mode_element):
+        Fix a couple of silly bugs.
+
+        * lread.c: New variable-defining functions
+        defvar_int, defvar_lisp, defvar_bool and defvar_per_buffer
+        are called by the new DEFVAR... macros.  They ignore the
+        doc-string argument.
+
+        * lisp.h: Define macros DEFVAR_LISP, DEFVAR_INT, DEFVAR_BOOL
+        and DEFVAR_PER_BUFFER.  They expand into calls to
+        defvar_lisp, etc.
+
+        * all .c files:
+        All Def...Var renamed to DEFVAR... in syms_of_....
+
+        * doc.c (FSnarf_documentation): Understand new DOC format
+        where doc for function foo is named Ffoo and doc for variable foo
+        is named Vfoo.  When doc for a variable is found, store the
+        file-position in DOC on the variable-documentation property.
+        * doc.c (Fdocumentation_property): New Lisp function,
+        like `get' except that if the value is a positive integer
+        it is taken as a position in the DOC file and a string is read
+        from that file.
+
+        * filelock.c: correct spelling "supercession" -> "supersession".
+
+        * undo.c: Rename RecordInsert as record_insert, and
+        likewise RecordDelete, RecordChange and RecordChange1.
+        * casefiddle.c, editfns.c, fileio.c, insdel.c: change callers.
+
+1986-08-19  Richard M. Stallman  (rms at prep)
+
+        * xdisp.c (display_mode_element):
+        Change the interpretation of symbols and lists in elements:
+        if a symbol's value is a string, output that string literally;
+        a list is a concatenation of all elements if the car is a string
+        or a conditional of the cdr if the car is a symbol.
+
+        * undo.c (Record...):
+        Remember buffer->modtime as the "length" of the Uunmod.
+        If point is at the end of a range deleted or changed,
+        record that as the "position" of the range and make the length
+        negative.
+
+        * undo.c (Fundo_more):
+        Undoing Uunmod does not mark as unmodified unless its
+        remembered modtime matches the buffer's current modtime.
+        Also handle case where length is negative in Uinsert, Uchange.
+
+1986-08-18  Richard Mlynarik  (mly at prep)
+
+        * xdisp.c (display_mode_line):
+        XSTRING->data, not XSTRING
+        Fix another typo.
+
+1986-08-17  Richard M. Stallman  (rms at prep)
+
+        * buffer.c (syms_of_buffer):
+        Change doc for mode-line-format.
+
+        * xdisp.c (display_mode_line, display_mode_element):
+        Allow buf->mode_line_format to contain lists and symbols
+        allowing computation and concatenation to produce the mode line.
+        (Note that evaluation is not allowed; it would be unsafe.)
+        display_mode_element is the recursion point for this.
+
+1986-08-17  Richard Mlynarik  (mly at prep)
+
+        * emacs.c (main)
+        Move init_environ up.
+
+        * window.c (Fwindow_point)
+        typo.   
+
+        * environ.c
+        New function getenv replaces un*x getenv
+
+1986-08-17  Richard M. Stallman  (rms at prep)
+
+        * window.c (Fwindow_point):
+        When WINDOW is the selected window and its buffer is selected too,
+        return current value of point.  The pointm field of the window
+        is not meaningful in such cases.
+
+        * unexec.c (write_segment):
+        If hit nonexistent page, must write zeros, not return.
+
+1986-08-17  Richard Mlynarik  (mly at prep)
+
+        * callproc.c, process.c (Fcall_process, create_process)
+        Use `alloca' versions of environment-hacking functions
+        (ie current_environ_size and get_current_environ rather than
+        current_environ and free_environ)
+
+        * emacs.c (main):
+        Call syms_of_environ, init_environ.
+
+        * config.h., config.h.dist
+        Increase PURESIZE again (sigh)  
+
+        * unexec.c (write_segment):
+        Kludgey coercions ("(int)") to get this line to compile:
+         nwrite = (((int) ptr + 128) & ~127) - (int) ptr;
+        Also changed incorrect ~128 to ~127.
+
+        * process.c:
+        New function Fprocess_list.
+
+1986-08-17  Richard M. Stallman  (rms at prep)
+
+        * crt0.c, alloca.s: Remove hack_sky (special for sun2)
+        and the call to it.  No longer needed since floating point
+        is no longer used.
+
+        * unexec.c: New compiler flag A_TEXT_OFFSET is defined
+        for machines in which the a.out file header counts as the
+        first few bytes of the text segment.  The definition of
+        A_TEXT_OFFSET would normally be sizeof (HDR).  It has
+        other terms added in on some machines (sequent).
+
+1986-08-16  Richard Mlynarik  (mly at prep)
+
+        * eval.c (Fmacroexpand)
+        Use car of nthcdr, not nth.
+
+        * fns.c
+        Define Fcopy_alist (used to be in subr.el)
+        Move Fnth to subr.el
+
+        * ymakefile
+        Include environ.c
+
+        * callproc.c, process.c (child_setup, Fcall_process, create_process):
+        Take/pass environment arg.
+
+        * environ.c:
+        New file
+
+        * sysdep.c:
+        Move VMS sys_getenv to environ.c
+
+        * editfns.c:
+        Move getenv to environ.c
+
+1986-08-16  Richard M. Stallman  (rms at prep)
+
+        * xdisp.c (display_text_line):
+        * indent.c (current_column, ToCol, position_indentation):
+        * indent.c (Fmove_to_column, compute_motion):
+        Bring tab_width in range if it is very large.
+
+1986-08-15  Richard M. Stallman  (rms at prep)
+
+        * fileio.c (Fwrite_region):
+        Do the fsync before the fstat; that may prevent what appear
+        to be spurious "file has changed on disk" warnings.
+        Update bf_cur->modtime before signaling "IO error writing"
+        to avoid more such warnings.
+
+        * Make ctl-arrow, case-fold-search, etc. behave exactly
+        as if they had been made local with make-variable-buffer-local.
+        The default values live in struct buffer buffer_defaults.
+        They also live in buffers that do not have local values.
+        Each buffer has a local_var_flags slot with a bit for each
+        variable, saying which variables are local in that buffer.
+
+        * buffer.h: New buffer slot local_var_flags.
+        * buffer.c: New structures buffer_defaults and buffer_local_flags.
+        (init_buffers_once): store default values for local slots
+        into buffer_defaults.
+        (reset_buffer_variables): Copy default values from buffer_defaults
+        into the buffer being reset.
+        (syms_of_buffer): Variables default-ctl-arrow, etc., now
+        forward to slots in buffer_defaults.
+
+        * data.c (Fset, Fset_default, Fdefault_value,
+        Fkill_local_variable):
+        Know that a Lisp_Buffer_Objfwd has default value
+        if the buffer_local_flags slot is nonzero,
+        and a buffer uses that default unless its local_var_flags
+        contains the bit of the buffer_local_flags for the slot.
+
+        * alloc.c (Fgarbage_collect): Call mark_buffer on buffer_defaults.
+
+1986-08-14  Richard M. Stallman  (rms at prep)
+
+        * unexec.c (copy_text_and_data):
+        Write text and data separately if COFF (just as if not COFF).
+        (make-hdr): if COFF and NO_REMAP, don't alter some f_ohdr fields.
+
+1986-08-14  Richard Mlynarik  (mly at prep)
+
+        * editfns.c (getenv)
+        Make getenv useful interactively.
+        Move defaliases to fsets in subr.el
+
+1986-08-14  Richard M. Stallman  (rms at prep)
+
+        * unexec.c: unexec_data_start records the ultimate
+        corrected data_start from make_hdr; copy_text_and_data
+        starts writing data segment from that address.
+
+1986-08-13  Richard M. Stallman  (rms at prep)
+
+        * buffer.c (Fkill_buffer): Combine Fdelete_buffer_internal
+        into this function.  Simplify.  Just return immediately
+        if attempted to kill the minibuffer.
+
+        * lisp.h: Define XSETPNTR and make XSETCONS (etc) use it.
+        By default XSETPNTR is the same as XSETUINT.
+
+        * lread.c (oblookup, map_obarray):
+        Use XUINT, not XSYMBOL, to check for zero to detect end of bucket.
+        On machines where all pointers have high bits set,
+        XSYMBOL would never return zero.
+
+        * alloc.c: change vars most_negative_fixnum and dont_copy_flag
+        to constant macros ARRAY_MARK_FLAG and DONT_COPY_FLAG,
+        defined normally based on INTBITS but overridable by m-*.h.
+
+        * process.c (handle_process_output):
+        Write in buffer even if buffer is read-only.
+
+        * fileio.c (barf_or_query_if_file_exists):
+        Rearrange: don't use comma around calls to NULL,
+        so can compile using union type.
+
+1986-08-12  Richard Mlynarik  (mly at prep)
+
+        * buffer.c (SetBfp, syms_of_buffer)
+        Dike out debug-check-symbol code.  I believe that this bug has
+        evaporated.
+
+        * fileio.c (barf_or_query_if_file_exists)
+        ! => !NULL.  Also use local variable for Lisp_object for bd
+        compilers.
+
+1986-08-11  Richard Mlynarik  (mly at prep)
+
+        * buffer.c (Fbarf_if_buffer_read_only)
+        Include buffer in call to Fsignal.
+
+        * print.c (Fwrite_char)
+        Really default stream to standard-output.
+
+1986-08-10  Richard Mlynarik  (mly at prep)
+
+        * eval.c (and abbrev.c, buffer.c, callint.c, cmds.c, keyboard.c, lread.c, lisp.h)
+        Allow Fapply to take an &rest arg, the last of which is spread.
+        (So (apply '+ 1 '(2 3)) => 6)
+        Make Ffuncall do the work for Fapply, rather than duplicating all
+        that code.  Define apply1 for c code which needs it.  Define call0
+        for c code which thought it needed Fapply.
+
+1986-08-08  Richard Mlynarik  (mly at prep)
+
+        * ymakefile
+        Don't assemble alloca.s if HAVE_ALLOCA.
+        Even though the whole of this file is contained in a
+        `#ifndef HAVE_ALLOCA ... #endif' a disgusting bug
+        in cc (at least here, vax 4.2bsd) meant that this
+        file was being assembled even though cc was passed
+        the -E flag!  Gag me with a unix-pinhead.
+
+        * m-vax.h
+        Define HAVE_ALLOCA if BSD
+
+        * unexec.c (write_segment)
+        Rename variable `fd' to `new' for macro PERROR.
+
+1986-07-30  Richard M. Stallman  (rms at prep)
+
+        * fileio.c (Fwrite_region): add call to fsync before close.
+
+        * xdisp.c (redisplay_window): Don't look at ->start
+        in windows that have subwindows, since it is nil there.
+
+        * window.c (save_window_restore):
+        Avoid doing Fset_buffer on a dead buffer.
+        Use the selected window's new current buffer in that case.
+
+1986-07-28  Richard M. Stallman  (rms at prep)
+
+        * fileio.c (Finsert_file_contents):
+        Don't mark buffer modified if inserted a null file.
+
+        * fileio.c (Fcopy_file, e_write): Use 16k buffer size.
+
+1986-07-17  Richard M. Stallman  (rms at prep)
+
+        * unexec.c (copy_sym): Put in missing #endif.
+
+        * alloc.c (Fpurecopy, mark_object): Flush VIRT_ADDR_VARIES
+        conditional; always use range from pure to pure + PURESIZE.
+        Use type PNTR_COMPARISON_TYPE as the type to compare in.
+        This is normally unsigned int but m- file may override this.
+
+        * lisp.h (CHECK_IMPURE): Use PNTR_COMPARISON_TYPE, and always
+        use the range from pure to pure + PURESIZE unless
+        PNTR_COMPARISON_TYPE is defaulted.
+
+        * eval.c (unbind_to): New temporary var `tmp'
+        to avoid a Gould compiler bug.
+
+        * term.c (calculate_ins_del_char_costs):
+        * window.c (change_window_height):
+        Changed floating point arithmetic to fixed point.
+
+        * sysdep.c: Replace ad-hoc conditionals with new flags
+        HAVE_VFORK, HAVE_DUP2 and HAVE_GETTIMEOFDAY.
+        Change s-hpux.h and m-stride.h.
+
+        * sysdep.c (init_sys_modes for VMS): Set TT2$M_XON.
+
+        * process.c (create_process): On USG systems that have TIOCNOTTY,
+        do the setpgrp here before reopening the pty rather than
+        waiting for child_setup.
+
+        * window.c (make_window): size given to make_vector
+        was one too small.
+
+1986-07-10  Richard M. Stallman  (rms at prep)
+
+        * keymap.c (Fdescribe_bindings): change XSETTYPE/XSETBUFFER to
+        XSET.
+        (describe_command): change XSETSTRING to XSET.
+        * window.c (Fmove_to_window_line): delete unused start =.
+        * xdisp.c (DoDsp) delete unused all_windows initializer.
+        * dispnew.c (update_line): delete unused osp =.
+        * minibuf.c (do_completion): delete unused completedp initializer.
+        * search.c (Freplace_match): delete unused some_multiletter_word init.
+        * alloc.c (gc_sweep): delete unused next initializers.
+        * fns.c (concat): after error on non-int elt for string,
+           do store the new value from the error handler.
+        * lread.c (read1): comment out unused end =.
+        * lread.c (read_list): delete unused tail =.
+        * data.c (Fmake_variable_buffer_local):
+          if value type is Lisp_Some_Buffer_Local_Value,
+          change it to Lisp_Buffer_Local_Value permanently.
+        * undo.c (record_block): delete unused cp =.
+          Don't bother reallocing if n = 0 after first batch.
+        * fileio.c (Fverify_visited_file_modtime):
+          If CHECK_BUFFER changes buf, use the changed value.
+
+1986-07-07  Richard M. Stallman  (rms at prep)
+
+        * alloc.c (mark_buffer): mark the selective_display_ellipses slot.
+
+1986-06-25  Richard M. Stallman  (rms at prep)
+
+        * window.c (Frecenter): Fix bug in last change:
+        change applied to M-- arg ratherthan C-u by mistake.
+
+1986-06-19  Richard M. Stallman  (rms at prep)
+
+        * ymakefile (CPP): Now defined by default as `cc -E'.
+        * Makefile: likewise.
+
+        * More 3b changes:
+        * ymakefile: Allow config to specify LIBS_TERMCAP even if
+        TERMINFO.
+        * sysdep.c: Delete the sign-extension functions; just define
+        a variable sign_extend_temp.
+        * m-3b.h renamed to m-3b20.h.  Now defines ATT3B20 as well as
+        ATT3B.  New definitions for XINT and SIGN_EXTEND_CHAR.
+
+        * sysdep.c (readdirver): New VMS-only function:
+        like readdir but return each version as separate filename.
+
+        * dired.c (file_name_completions): New arg ver_flag.
+        All callers changed.
+        * dired.c (Ffile_name_all_versions): New function, VMS only.
+
+        * unexec.c (copy_sym): Remove spurious #else on
+        sun3 conditional.  The old #else code is now unconditional.
+
+        * window.c (Fdisplay_window): Split largest window only if
+        full screen width.  The conditional was backwards.
+
+1986-06-17  Richard M. Stallman  (rms at prep)
+
+        * process.c (Fsend_region): Previous change forgot to assign
+        anything to start1.
+
+1986-06-13  Richard M. Stallman  (rms at prep)
+
+        * emacs.c (Fdump_emacs): Use start_of_text, not &_start,
+        as entry address for unexec.
+
+        * alloc.c: Use XPNTR, not XUINT, when checking for pureness.
+
+        * data.c: When indirecting through Lisp_Buffer_Objfwd,
+        use XUINT to get the offset, not XOBJFWD.
+
+        * lisp.h: New macro XPNTR is used as subroutine by all of
+        XCONS, XSTRING, etc.  Define it like XUINT normally.
+        If DATA_SEG_BITS is defined, XPNTR or's that into the result.
+        Use XPNTR in CHECK_IMPURE.
+
+        * sysdep.c (end_of_{text,data}): Do compile these.
+        rt-pc unexec needs them.
+        * sysdep.c (start_of_bss): New function.
+
+        * unexec.c (copy_text_and_data, write_segment):
+        Write text and data segments separately.
+        Use new subroutine write_segment to do each one.
+
+        * process.c (Fprocess_exit_status):
+        New name for Fprocess_reason.
+
+1986-06-11  Richard M. Stallman  (rms at prep)
+
+        * abbrev.c (Fexpand_abbrev):
+        Delete the - inserted by abbrev-prefix-mark, if any.
+
+        * filelock.c (lock_file):
+        Check for modifying a buffer whose file has changed
+        and call ask-user-about-supercession-threat, which can
+        ask for confirmation and get an error.
+
+1986-06-10  Richard M. Stallman  (rms at prep)
+
+        * crt0.c: Merge changes for Nu.
+
+        * unexec.c (make_hdr): Fix handling of blockcopy_start;
+        for the sake of Nu machine.
+
+        * fileio.c (Fcopy_file): optional 4th arg non-nil
+        means preserve the last-modified time.
+
+        * Make C-M-v in minibuffer scroll the minibuffer's help window if any.
+        * window.c (save_window_{save,restore}):
+        Save and restore minibuf_scroll_window.
+        * window.c (Fscroll_other_window):
+        If minibuffer is selected, scroll minibuf_scroll_window.
+        * minibuf.c (read_minibuf): set minibuf_scroll_window to nil.
+
+        * window.c (Frecenter): With just C-u as arg,
+        recenter point but don't erase the screen.
+
+1986-06-09  Richard M. Stallman  (rms at prep)
+
+        * process.c (Fsend_region):
+        * fileio.c (Fwrite_region):
+        * editfns.c (Fchar_after, save_restriction_restore):
+        Avoid using XINT in args to other macros.
+
+        * sysdep.c: New function char_sign_xtnd for ATT3B.
+
+        * lisp.h: Don't redefine XINT if it's already defined.
+        So m-3b.h can override it.
+
+        * ymakefile: If NO_REMAP, use the standard crt0.o
+        but precede it with pre_crt0.o whose job is to define data_start.
+
+        * buffer.h. buffer.c: New per-buffer variable 
+        selective-display-ellipses.
+
+        * xdisp.c (display_text_line), indent.c (compute_motion):
+        Let bf_cur->selective_display_ellipses control display of ...
+        before invisible lines.
+
+        * lread.c (openp, Fload): openp now takes a sequence
+        of suffixes with colons between.  It loops over
+        suffixes faster than over directories.
+        load takes new fourth arg NOSUFFIXES.
+
+1986-06-08  Richard M. Stallman  (rms at prep)
+
+        * paths.h: Remove . from load-path.
+
+        * lread.c: Make "load" no longer interactive.
+
+        * keyboard.c: Introduce BUFFER_SIZE_FACTOR to make
+        some keyboard buffers 16 times as big when X windows exist.
+
+1986-06-07  Richard M. Stallman  (rms at prep)
+
+        * eval.c (call_debugger): Don't do a debug-on-call
+        for calling the debugger.
+
+        * keyboard.c (gobble_input): Must really use FIONREAD.
+
+        * keyboard.c (command_loop{,_1,_2}, top_level_{1,2}):
+        Now Frecursive_edit calls command_loop, which does the catches
+        and calls command_loop_2, which does the error handling,
+        which calls command_loop to do the real work.
+        Also, top_level_1 does a condition-case around top_level_2,
+        which does the work.
+
+        Previously, the error handling was outside the catch for
+        top-level.  Then if handling an error ran an unwind protect form,
+        the catch was not in effect; so ^G, or the debugger Q command,
+        would not work inside of them.
+
+1986-06-06  Richard M. Stallman  (rms at prep)
+
+        * keymap.c (get_keymap{,_1}):
+        Create get_keymap_1 that takes arg saying whether to get error.
+        get_keymap calls that, saying do get an error.
+
+        * keyboard.c (get_char):
+        If rereading a char, do put it in the echo buffer
+        if the echo buffer is empty.  Fixes problem that
+        C-s C-h would never echo the C-h.
+
+        * window.h: New window slot start_at_line_beg,
+        holds t if window's start was the beginning of a line.
+        * window.c: update this wherever ->start is updated.
+        (But not always correctly).
+        * xdisp.c (redisplay_window): update start_at_line_beg,
+        and also find a new start if the old start used to be
+        a line beginning but no longer is (which implies text
+        changes just before it).
+
+        * keyboard.c (get_input_pending):
+        Don't bother with FIONREAD if interrupt_input;
+        just use kbd_count.
+
+        * fns.c: Assume KERNEL_FILE, LDAV_SYMBOL and NLIST_STRUCT
+        are fully set up by the s- and m- files.
+
+        * emacs.c (main): Don't call `signal' if in batch mode
+        and not initialized and dumping is possible.
+        * keyboard.c (init_keyboard): likewise for SIGIO.
+
+        * unexec.c (make_hdr): Copy entire header of old file
+        as base for header of new file.  Eliminates most
+        machine-specific conditionals.
+
+        * terminfo.c: make tparam work by calling tparm.
+
+        * term.c, cm.h: Eliminate `Tab' macro.
+
+        * s-usg5.2.h, s-usg5.2.2.h: set the TERMINFO flag.
+
+        * fileio.c (Ffile_newer_than_file_p): New Lisp primitive.
+
+        * fileio.c (Ffile_exists_p):  this is now distinct from
+        Ffile_readable_p; it checks only for existence, not for
+        readability.
+
+        * editfns.c (Fgoto_char): Use new interactive code N.
+
+        * callint.c (Fcall_interactively): New code N
+        means use prefix argif have one, else read number from minibuffer.
+
+        * buffer.c (record_buffer):
+        Don't use Frassq, Fmemq or Fdelq since their loops
+        allow quitting.  Write a spacial loop by hand.
+
+1986-06-05  Richard M. Stallman  (rms at prep)
+
+        * process.c: Add MASSCOMP conditionals for pty and tty names.
+        New way to check pty accessibility with `access'.
+
+        * unexec.c (make_hdr): MASSCOMP has its own special field.
+
+        * sysdep.c: Use HAVE_TERMIO conditionals instead of USG
+        conditionals in many places.  Use INTERRUPTABLE_OPEN
+        and INTERRUPTABLE_IO conditionals to decide whether to
+        include the functions sys_read, sys_write, sys_open.
+        child_setup_tty must do FIOASYNC on masscomp.
+
+        * fns.c (concat): Add MASSCOMP_REGISTER_BUG conditional.
+
+        * editfns.c (init_editfns): Always check LOGNAME if no USER var.
+
+        * dispnew.c: Now depends on HAVE_TERMIO.
+
+        * crt0.c: BOGUS flag renamed CRT0_DUMMIES.  Also now
+        this is never assumes; each m- file must set it to use that code.
+
+        * crt0.c: Two new flags: GLOBAL_START_DOT and
+        GLOBAL_START_NO_DOT, control .globl start, etc.
+        m- files must define these as needed.
+        To have no effect, must define one or the other whenever
+        CRT0_DUMMIES is set except for masscomp.
+        GLOBAL_START_NO_DOT for tower32, GLOBAL_START_DOT for all others.
+
+        * term.c, termchar.h: Define new flag var no_redraw_on_reenter;
+        nonzero means no need to set screen_garbaged on resuming
+        after a suspension.
+        * sysdep.c (init_sys_modes): don't set screen_garbaged
+        after resumption if that flag is set.
+        * dispnew.c (syms_of_dispnew): make Lisp var no-redraw-on-reenter,
+
+        * process.c (Fprocess_reason): New function.
+
+        * dispnew.c (change_screen_size): New arg PRETEND.
+        If it's zero, set ScreenRows or ScreenCols.
+        Fset_screen_{width,height} take new arg as well
+        to control value of PRETEND.
+
+        * sysdep.c (child_setup_tty for USG):
+        Turn ICANON on, and set VKILL and VERASE to 0377.
+        Don't frob VMIN and VTIME (said to be unnecessary here).
+
+        * keyboard.c (command_loop, Frecursive_edit):
+        Call top_level_1 only from command_loop.
+        Do it before command_loop_1.  Put catch for top-level around it.
+
+        * xdisp.c (try_window_1): use scroll_cost to decide
+        whether scrolling, as determined from ins/del records,
+        is better than simple reprinting.
+
+        * scroll.c (scroll_cost): New function computes what cost
+        would be to do scroll_screen_lines.
+
+        * xdisp.c (display_text_string):
+        Display minibuf_prompt only if vpos is the top of the minibuffer.
+        Attempts to fix the bug where the prompt appears on all the
+        lines of an empty minibuffer.
+
+1986-06-04  Richard M. Stallman  (rms at prep)
+
+        * fileio.c (Fdefine_logical_name):
+        For VMS: create a logical name translation.
+
+        * emacs.c (main):
+        (HAVE_X_WINDOWS) New variable alternate_display,
+        set with a -d switch.
+
+        * keyboard.c, sysdep.c:
+        Create new system-independent function sys_suspend.
+        All places that want to suspend now use sys_suspend.
+        Delete fake_suspend and make its definition one of the
+        cases for sys_suspend; but require the caller to change
+        the terminal modes, on all system versions.
+
+        * Merged in VMS conditionals in numerous files.
+
+1986-06-01  Richard M. Stallman  (rms at prep)
+
+        * emacs.c (main, Fdump_emacs):
+        Use new arg to malloc_init to say what function to call for
+        warnings.
+
+        * unexec.c, malloc.c, getpagesize.h:
+        The code to define getpagesize () is now in getpagesize.h.
+
+        * process.c (reate_process), callproc.c (child_setup):
+        Move call to child_setup_tty from child_setup to create_process,
+        so it's not done for synchronous subprocesses.
+        * sysdep.c (child_setup_tty): omit it if not subprocesses.
+
+        * alloc.c (mark_object), lread.c (DefLispVar):
+        Protect the C variable with staticpro.
+        Therefore no more need to mark thru a Lisp_Objfwd.
+
