        Assume freestanding C89 headers, string.h, stdlib.h.
        Again, this simplifies the code, and all current platforms have these.

+        * lib/stdint.in.h: Merge from gnulib (Bug#9025).
+        This fixes a build problem on older Mac OS X hosts.
+        * m4/pthread_sigmask.m4 (gl_FUNC_PTHREAD_SIGMASK): Omit gl_THREADLIB
+        test, which runs afoul of Automake installations where, for example,
+        /usr/share/aclocal contains a copy of gl_THREADLIB.
+        Problem reported by Sven Joachim in
+        <http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00529.html>.
+        This is just a quick temporary fix, specific to Emacs; I'll work
+        with the other gnulib maintainers to get a more-permanent fix.
        Add gnulib's strtoimax module, needed on Solaris 8.
        * Makefile.in (GNULIB_MODULES): Add strtoimax.
        * lib/strtoll.c, m4/strtoimax.m4, m4/strtoll.m4: New files,

-@node Minor Modes
-@section Minor Modes
-@cindex minor modes
-@cindex mode, minor
-  Minor modes are optional features which you can turn on or off.  For
-example, Auto Fill mode is a minor mode in which @key{SPC} breaks
-lines between words as you type.  Minor modes are independent of one
-another and of the selected major mode.  Most minor modes say in the
-mode line when they are enabled; for example, @samp{Fill} in the mode
-line means that Auto Fill mode is enabled.
-  Each minor mode is associated with a command, called the @dfn{mode
-command}, which turns it on or off.  The name of this command consists
-of the name of the minor mode, followed by @samp{-mode}; for instance,
-the mode command for Auto Fill mode is @code{auto-fill-mode}.  Calling
-the minor mode command with no prefix argument @dfn{toggles} the mode,
-turning it on if it was off, and off if it was on.  A positive
-argument always turns the mode on, and a zero or negative argument
-always turns it off.  Mode commands are usually invoked with
-@kbd{M-x}, but you can bind keys to them if you wish (@pxref{Key
-Bindings}).
-  Most minor modes also have a @dfn{mode variable}, with the same name
-as the mode command.  Its value is non-@code{nil} if the mode is
-enabled, and @code{nil} if it is disabled.  In some minor modes---but
-not all---the value of the variable alone determines whether the mode
-is active: the mode command works simply by setting the variable, and
-changing the value of the variable has the same effect as calling the
-mode command.  Because not all minor modes work this way, we recommend
-that you avoid changing the mode variables directly; use the mode
-commands instead.
-  Some minor modes are @dfn{buffer-local}: they apply only to the
-current buffer, so you can enable the mode in certain buffers and not
-others.  Other minor modes are @dfn{global}: while enabled, they
-affect everything you do in the Emacs session, in all buffers.  Some
-global minor modes are enabled by default.
-  The following is a list of some buffer-local minor modes:
-@itemize @bullet
-@item
-Abbrev mode automatically expands text based on pre-defined
-abbreviation definitions.  @xref{Abbrevs}.
-@item
-Auto Fill mode inserts newlines as you type to prevent lines from
-becoming too long.  @xref{Filling}.
-@item
-Auto Save mode saves the buffer contents periodically to reduce the
-amount of work you can lose in case of a crash.  @xref{Auto Save}.
-@item
-Enriched mode enables editing and saving of formatted text.
-@xref{Formatted Text}.

-Flyspell mode automatically highlights misspelled words.
-@xref{Spelling}.
-@item
-Font-Lock mode automatically highlights certain textual units found in
-programs.  It is enabled globally by default, but you can disable it
-in individual buffers.  @xref{Faces}.
-@findex linum-mode
-@cindex Linum mode
-@item
-Linum mode displays each line's line number in the window's left
-margin.  Its mode command is @code{linum-mode}.
-@item
-Outline minor mode provides similar facilities to the major mode
-called Outline mode.  @xref{Outline Mode}.
-@cindex Overwrite mode
-@cindex mode, Overwrite
-@findex overwrite-mode
-@kindex INSERT
-@item
-Overwrite mode causes ordinary printing characters to replace existing
-text instead of shoving it to the right.  For example, if point is in
-front of the @samp{B} in @samp{FOOBAR}, then in Overwrite mode typing
-a @kbd{G} changes it to @samp{FOOGAR}, instead of producing
-@samp{FOOGBAR} as usual.  In Overwrite mode, the command @kbd{C-q}
-inserts the next character whatever it may be, even if it is a
-digit---this gives you a way to insert a character instead of
-replacing an existing character.  The mode command,
-@code{overwrite-mode}, is bound to the @key{Insert} key.
-@findex binary-overwrite-mode
-@item
-Binary Overwrite mode is a variant of Overwrite mode for editing
-binary files; it treats newlines and tabs like other characters, so
-that they overwrite other characters and can be overwritten by them.
-In Binary Overwrite mode, digits after @kbd{C-q} specify an octal
-character code, as usual.
-@item
-Visual Line mode performs ``word wrapping'', causing long lines to be
-wrapped at word boundaries.  @xref{Visual Line Mode}.
-@end itemize
-  Here are some useful global minor modes.  Since Line Number mode and
-Transient Mark mode can be enabled or disabled just by setting the
-value of the minor mode variable, you @emph{can} set them differently
-for particular buffers, by explicitly making the corresponding
-variable local in those buffers.  @xref{Locals}.
-@itemize @bullet
-@item
-Column Number mode enables display of the current column number in the
-mode line.  @xref{Mode Line}.
-@item
-Delete Selection mode causes text insertion to first delete the text
-in the region, if the region is active.  @xref{Using Region}.
-@item
-Icomplete mode displays an indication of available completions when
-you are in the minibuffer and completion is active.  @xref{Completion
-Options}.
-@item
-Line Number mode enables display of the current line number in the
-mode line.  It is enabled by default.  @xref{Mode Line}.
-@item
-Menu Bar mode gives each frame a menu bar.  It is enabled by default.

-@item
-Scroll Bar mode gives each window a scroll bar.  It is enabled by

-Tool Bar mode gives each frame a tool bar.  It is enabled by default,

-@section The Syntax Table
-@cindex syntax table
-  All the Emacs commands which parse words or balance parentheses are
-controlled by the @dfn{syntax table}.  The syntax table says which
-characters are opening delimiters, which are parts of words, which are
-string quotes, and so on.  It does this by assigning each character to
-one of fifteen-odd @dfn{syntax classes}.  In some cases it specifies
-some additional information also.
-  Each major mode has its own syntax table (though related major modes
-sometimes share one syntax table), which it installs in each buffer
-that uses the mode.  The syntax table installed in the current buffer
-is the one that all commands use, so we call it ``the'' syntax table.

-starting with the character which designates its syntax class, plus

-  When running Emacs under the X window system, you can easily
-transfer text between Emacs and other X applications using the
-@dfn{primary selection} (also called the @dfn{X selection}).  This is
-@emph{not} the same thing as the @dfn{clipboard}, which is a separate
-facility used on desktop environments such as Gnome, and on operating
-systems such as Microsoft Windows (@pxref{Clipboard}).
-  Under X, whenever you select some text in Emacs by dragging or
-clicking the mouse (@pxref{Mouse Commands}), it is also saved in the
-primary selection.  You can then @dfn{paste} that text into any other
-X application, usually by clicking @kbd{Mouse-2} in that application.
-Unlike the Emacs kill ring (@pxref{Kill Ring}), the primary selection
-has no ``memory'': each time you save something in the primary
-selection, either in Emacs or in another X application, the previous
-contents of the primary selection are lost.
-@cindex MS-Windows, and primary selection
-  MS-Windows provides no primary selection, but Emacs emulates it
-within a single Emacs session, by storing the selected text
-internally.  Therefore, all the features and commands related to the
-primary selection work on Windows as they do on X, for cutting and
-pasting within the same session, but not across Emacs sessions or with
-other applications.
-  Whenever you kill some text using a command such as @kbd{C-w}
-(@code{kill-region}), or copy it into the kill ring using a command
-such as @kbd{M-w} (@code{kill-ring-save}), that text is also saved in
-the primary selection.  @xref{Killing}.
-@vindex select-active-regions
-  If you set the region using the keyboard---for instance, by typing
-@kbd{C-@key{SPC}} and moving point away from the mark---the text in
-the region is not normally saved to the primary selection.  However,
-if you change the variable @code{select-active-regions} to @code{t},
-the region is saved to the primary selection whenever you activate the
-mark.  Each change to the region also updates the primary selection.
-@vindex yank-pop-change-selection
-  If you change @code{yank-pop-change-selection} to @code{t}, rotating
-the kill ring with @kbd{M-y} (@code{yank-pop}) also saves the new yank
-to the primary selection (@pxref{Yanking}).
-@vindex save-interprogram-paste-before-kill
-  If you change @code{save-interprogram-paste-before-kill} to
-@code{t}, each kill command first saves the existing selection onto
-the kill ring.  This prevents you from losing the existing selection,
-at the risk of large memory consumption if other applications generate
-large selections.
-  You can yank the primary selection into Emacs using the usual yank
-commands, such as @kbd{C-y} (@code{yank}) and @kbd{Mouse-2}
-(@code{mouse-yank-at-click}).  These commands actually check the
-primary selection before referring to the kill ring; if no primary
-selection is available, the kill ring contents are used.  To prevent
-yank commands from accessing the primary selection, set the variable
-@code{x-select-enable-primary} to @code{nil}.
-  The standard coding system for the primary selection is
-@code{compound-text-with-extensions}.  You may find that the pasted
-text is not what you expected.  In such a case, you can specify
-another coding system for the selection by typing @kbd{C-x @key{RET}
-x} or @kbd{C-x @key{RET} X}.  Alternatively, you can request a
-different data type by modifying the variable
-@code{x-select-request-type}.  @xref{Communication Coding}.
-@node Secondary Selection
-@subsection Secondary Selection
-@cindex secondary selection
-  In addition to the primary selection, the X Window System provides a
-second similar facility known as the @dfn{secondary selection}.
-Nowadays, few X applications make use of the secondary selection, but
-you can access it using the following Emacs commands:
-@table @kbd
-@findex mouse-set-secondary
-@kindex M-Drag-Mouse-1
-@item M-Drag-Mouse-1
-Set the secondary selection, with one end at the place where you press
-down the button, and the other end at the place where you release it
-(@code{mouse-set-secondary}).  The selected text is highlighted, using
-the @code{secondary-selection} face, as you drag.  The window scrolls
-automatically if you drag the mouse off the top or bottom of the
-window, just like @code{mouse-set-region} (@pxref{Mouse Commands}).
-This command does not alter the kill ring.
-@findex mouse-start-secondary
-@kindex M-Mouse-1
-@item M-Mouse-1
-Set one endpoint for the @dfn{secondary selection}

-@item M-Mouse-3
-Set the secondary selection, with one end at the position clicked and

-(@code{mouse-secondary-save-then-kill}).  This also puts the selected
-text in the kill ring.  A second @kbd{M-Mouse-3} at the same place
-kills the secondary selection just made.
-@findex mouse-yank-secondary
-@kindex M-Mouse-2
-@item M-Mouse-2

-@node Clipboard
-@subsection Using the Clipboard
-@cindex clipboard
-  In desktop environments such as Gnome, and operating systems such as
-Microsoft Windows and Mac OS X, you can transfer data (usually text)
-between different applications using the @dfn{clipboard}.  The
-clipboard is distinct from the primary selection and secondary
-selection discussed earlier.  You can access the clipboard through the
-@samp{Edit} menu of the menu bar (@pxref{Menu Bar}).
-@cindex cut
-@findex clipboard-kill-region
-  The command @code{clipboard-kill-region}, which is bound to the
-@code{Cut} menu item, kills the region and saves it in the clipboard.
-@cindex copy
-@findex clipboard-kill-ring-save
-  The command @code{clipboard-kill-ring-save}, which is bound to the
-@code{Copy} menu item, copies the region to the kill ring and saves it

-@findex clipboard-yank
-@cindex paste
-  The @code{Paste} menu item in the Edit menu yanks the contents of
-the clipboard at point (@code{clipboard-yank}).
-@vindex x-select-enable-clipboard
-  You can customize the variable @code{x-select-enable-clipboard} to
-make the Emacs yank functions consult the clipboard before the primary
-selection, and to make the kill functions to store in the clipboard as
-well as the primary selection.  Otherwise, these commands do not
-access the clipboard at all.  Using the clipboard is the default on
-MS-Windows and Mac OS, but not on other systems.

+@node Clipboard
+@subsection Using the Clipboard
+@cindex clipboard
+  The @dfn{clipboard} is the facility that most graphical applications
+use for ``cutting and pasting''.  When the clipboard exists, the kill
+and yank commands in Emacs make use of it.
+  When you kill some text with a command such as @kbd{C-w}
+(@code{kill-region}), or copy it to the kill ring with a command such
+as @kbd{M-w} (@code{kill-ring-save}), that text is also put in the
+clipboard.  @xref{Killing}.
+@vindex save-interprogram-paste-before-kill
+  When an Emacs kill command puts text in the clipboard, the existing
+clipboard contents are normally lost.  Optionally, you can change
+@code{save-interprogram-paste-before-kill} to @code{t}.  Then Emacs
+will first save the clipboard to its kill ring, preventing you from
+losing the old clipboard data---at the risk of high memory consumption
+if that data turns out to be large.
+  The usual yank commands, such as @kbd{C-y} (@code{yank}), also use
+the clipboard.  If another application ``owns'' the clipboard---i.e.,
+if you cut or copied text there more recently than your last kill
+command in Emacs---then Emacs yanks from the clipboard instead of the
+kill ring.  Otherwise, it yanks from the kill ring, as described in
+@ref{Yanking}.
+@vindex yank-pop-change-selection
+  Normally, rotating the kill ring with @kbd{M-y} (@code{yank-pop})
+does not alter the clipboard.  However, if you change
+@code{yank-pop-change-selection} to @code{t}, then @kbd{M-y} saves the
+new yank to the clipboard.
+@vindex x-select-enable-clipboard
+  To prevent kill and yank commands from accessing the clipboard,
+change the variable @code{x-select-enable-clipboard} to @code{nil}.
+@vindex x-select-enable-primary
+@findex clipboard-kill-region
+@findex clipboard-kill-ring-save
+@findex clipboard-yank
+  Prior to Emacs 24, the kill and yank commands used the primary
+selection (@pxref{Primary Selection}), not the clipboard.  If you
+prefer this behavior, change @code{x-select-enable-clipboard} to
+@code{nil}, @code{x-select-enable-primary} to @code{t}, and
+@code{mouse-drag-copy-region} to @code{t}.  In this case, you can use
+the following commands to act explicitly on the clipboard:
+@code{clipboard-kill-region} kills the region and saves it to the
+clipboard; @code{clipboard-kill-ring-save} copies the region to the
+kill ring and saves it to the clipboard; and @code{clipboard-yank}
+yanks the contents of the clipboard at point.
+@node Primary Selection
+@subsection Cut and Paste with Other Window Applications
+@cindex X cutting and pasting
+@cindex X selection
+@cindex primary selection
+@cindex selection, primary
+  Under the X window system, there exists a @dfn{primary selection}
+containing the last stretch of text selected in an X application
+(usually by dragging the mouse).  Typically, this text can be inserted
+into other X applications by @kbd{mouse-2} clicks.  The primary
+selection is separate from the clipboard (@pxref{Clipboard}).  Its
+contents are more ``fragile''; they are overwritten by any mouse
+selection, whereas the clipboard is only overwritten by explicit
+``cut'' or ``copy'' commands.
+  Under X, whenever you select some text in Emacs by dragging or
+clicking the mouse (@pxref{Mouse Commands}), it is also saved to the
+primary selection.
+@vindex select-active-regions
+  If you set the region using the keyboard---for instance, by typing
+@kbd{C-@key{SPC}} and moving point away from the mark---the text in
+the region is also saved to the primary selection.  (The updating of
+the primary selection is done at the end of each command, as long as
+the region is active and non-empty.)  To disable this behavior, change
+the variable @code{select-active-regions} to @code{nil}.
+  To insert the primary selection into an Emacs buffer, click
+@kbd{mouse-2} (@code{mouse-yank-primary}) where you want to insert it.
+@xref{Mouse Commands}.
+@cindex MS-Windows, and primary selection
+  MS-Windows provides no primary selection, but Emacs emulates it
+within a single Emacs session by storing the selected text internally.
+Therefore, all the features and commands related to the primary
+selection work on Windows as they do on X, for cutting and pasting
+within the same session, but not across Emacs sessions or with other
+applications.
+@node Secondary Selection
+@subsection Secondary Selection
+@cindex secondary selection
+  In addition to the primary selection, the X Window System provides a
+second similar facility known as the @dfn{secondary selection}.
+Nowadays, few X applications make use of the secondary selection, but
+you can access it using the following Emacs commands:
+@table @kbd
+@findex mouse-set-secondary
+@kindex M-Drag-Mouse-1
+@item M-Drag-Mouse-1
+Set the secondary selection, with one end at the place where you press
+down the button, and the other end at the place where you release it
+(@code{mouse-set-secondary}).  The selected text is highlighted, using
+the @code{secondary-selection} face, as you drag.  The window scrolls
+automatically if you drag the mouse off the top or bottom of the
+window, just like @code{mouse-set-region} (@pxref{Mouse Commands}).
+This command does not alter the kill ring.
+@findex mouse-start-secondary
+@kindex M-Mouse-1
+@item M-Mouse-1
+Set one endpoint for the @dfn{secondary selection}
+(@code{mouse-start-secondary}).
+@findex mouse-secondary-save-then-kill
+@kindex M-Mouse-3
+@item M-Mouse-3
+Set the secondary selection, with one end at the position clicked and
+the other at the position specified with @kbd{M-Mouse-1}
+(@code{mouse-secondary-save-then-kill}).  This also puts the selected
+text in the kill ring.  A second @kbd{M-Mouse-3} at the same place
+kills the secondary selection just made.
+@findex mouse-yank-secondary
+@kindex M-Mouse-2
+@item M-Mouse-2
+Insert the secondary selection where you click, placing point at the
+end of the yanked text (@code{mouse-yank-secondary}).
+@end table
+Double or triple clicking of @kbd{M-Mouse-1} operates on words and
+lines, much like @kbd{Mouse-1}.
+If @code{mouse-yank-at-point} is non-@code{nil}, @kbd{M-Mouse-2} yanks
+at point.  Then it does not matter precisely where you click, or even
+which of the frame's windows you click on.  @xref{Mouse Commands}.

-@cindex mode, major
-@kindex TAB @r{(and major modes)}
-@kindex DEL @r{(and major modes)}
-@kindex C-j @r{(and major modes)}
-  Emacs provides many alternative @dfn{major modes}, each of which
-customizes Emacs for editing text of a particular sort.  The major modes
-are mutually exclusive, and each buffer has one major mode at any time.
-The mode line normally shows the name of the current major mode, in
-parentheses (@pxref{Mode Line}).
-  The least specialized major mode is called @dfn{Fundamental mode}.
-This mode has no mode-specific redefinitions or variable settings, so
-that each Emacs command behaves in its most general manner, and each
-user option variable is in its default state.  For editing text of a
-specific type that Emacs knows about, such as Lisp code or English
-text, you should switch to the appropriate major mode, such as Lisp
-mode or Text mode.
-  Selecting a major mode changes the meanings of a few keys to become
-more specifically adapted to the language being edited.  The ones that
-are changed frequently are @key{TAB}, @key{DEL}, and @kbd{C-j}.  The
-prefix key @kbd{C-c} normally contains mode-specific commands.  In
-addition, the commands which handle comments use the mode to determine
-how comments are to be delimited.  Many major modes redefine the
-syntactical properties of characters appearing in the buffer.
-@xref{Syntax}.
-  The major modes fall into three major groups.  The first group
-contains modes for normal text, either plain or with mark-up.  It
-includes Text mode, HTML mode, SGML mode, @TeX{} mode and Outline
-mode.  The second group contains modes for specific programming
-languages.  These include Lisp mode (which has several variants), C
-mode, Fortran mode, and others.  The remaining major modes are not
-intended for use on users' files; they are used in buffers created for
-specific purposes by Emacs, such as Dired mode for buffers made by
-Dired (@pxref{Dired}), Message mode for buffers made by @kbd{C-x m}
-(@pxref{Sending Mail}), and Shell mode for buffers used for
-communicating with an inferior shell process (@pxref{Interactive
-Shell}).
-  Most programming-language major modes specify that only blank lines
-separate paragraphs.  This is to make the paragraph commands useful.
-(@xref{Paragraphs}.)  They also cause Auto Fill mode to use the
-definition of @key{TAB} to indent the new lines it creates.  This is
-because most lines in a program are usually indented
-(@pxref{Indentation}).
-@menu
-* Choosing Modes::     How major modes are specified or chosen.
-@end menu
-@node Choosing Modes,,Major Modes,Major Modes
-@section How Major Modes are Chosen
-@cindex choosing a major mode
-  You can select a major mode explicitly for the current buffer, but
-most of the time Emacs determines which mode to use based on the file
-name or on special text in the file.
-  To explicitly select a new major, you use an @kbd{M-x} command.
-Take the name of a major mode and add @code{-mode} to get the name of
-the command to select that mode.  Thus, you can enter Lisp mode by
-executing @kbd{M-x lisp-mode}.
-@vindex auto-mode-alist
-  When you visit a file, Emacs usually chooses the right major mode
-automatically.  Normally, it makes the choice based on the file
-name---for example, files whose names end in @samp{.c} are normally
-edited in C mode---but sometimes it chooses the major mode based on
-the contents of the file.  Here is the exact procedure:
-  First, Emacs checks whether the file contains a file-local variable
-that specifies the major mode.  If so, it uses that major mode,
-ignoring all other criteria.  @xref{File Variables}.  There are
-several methods to specify a major mode using a file-local variable;
-the simplest is to put the mode name in the first nonblank line,
-preceded and followed by @samp{-*-}.  Other text may appear on the
-line as well.  For example,
-@example
-; -*-Lisp-*-
-@end example
-@noindent
-tells Emacs to use Lisp mode.  Note how the semicolon is used to make
-Lisp treat this line as a comment.  Alternatively, you could write
-@example
-; -*- mode: Lisp;-*-
-@end example
-@noindent
-The latter format allows you to specify local variables as well, like
-this:
-@example
-; -*- mode: Lisp; tab-width: 4; -*-
-@end example
-@vindex interpreter-mode-alist
-  Second, Emacs checks whether the file's contents begin with
-@samp{#!}.  If so, that indicates that the file can serve as an
-executable shell command, which works by running an interpreter named
-on the file's first line (the rest of the file is used as input to the
-interpreter).  Therefore, Emacs tries to use the interpreter name to
-choose a mode.  For instance, a file that begins with
-@samp{#!/usr/bin/perl} is opened in Perl mode.  The variable
-@code{interpreter-mode-alist} specifies the correspondence between
-interpreter program names and major modes.
-  When the first line starts with @samp{#!}, you usually cannot use
-the @samp{-*-} feature on the first line, because the system would get
-confused when running the interpreter.  So Emacs looks for @samp{-*-}
-on the second line in such files as well as on the first line.  The
-same is true for man pages which start with the magic string
-@samp{'\"} to specify a list of troff preprocessors.
-@vindex magic-mode-alist
-  Third, Emacs tries to determine the major mode by looking at the
-text at the start of the buffer, based on the variable
-@code{magic-mode-alist}.  By default, this variable is @code{nil} (an
-empty list), so Emacs skips this step; however, you can customize it
-in your init file (@pxref{Init File}).  The value should be a list of
-elements of the form
-@example
-(@var{regexp} . @var{mode-function})
-@end example
-@noindent
-where @var{regexp} is a regular expression (@pxref{Regexps}), and
-@var{mode-function} is a Lisp function that toggles a major mode.  If
-the text at the beginning of the file matches @var{regexp}, Emacs
-chooses the major mode specified by @var{mode-function}.
-Alternatively, an element of @code{magic-mode-alist} may have the form
-@example
-(@var{match-function} . @var{mode-function})
-@end example
-@noindent
-where @var{match-function} is a Lisp function that is called at the
-beginning of the buffer; if the function returns non-@code{nil}, Emacs
-set the major mode wit @var{mode-function}.
-  Fourth---if Emacs still hasn't found a suitable major mode---it
-looks at the file's name.  The correspondence between file names and
-major modes is controlled by the variable @code{auto-mode-alist}.  Its
-value is a list in which each element has this form,
-@example
-(@var{regexp} . @var{mode-function})
-@end example
-@noindent
-or this form,
-@example
-(@var{regexp} @var{mode-function} @var{flag})
-@end example
-@noindent
-For example, one element normally found in the list has the form
-@code{(@t{"\\.c\\'"} . c-mode)}, and it is responsible for selecting C
-mode for files whose names end in @file{.c}.  (Note that @samp{\\} is
-needed in Lisp syntax to include a @samp{\} in the string, which must
-be used to suppress the special meaning of @samp{.} in regexps.)  If
-the element has the form @code{(@var{regexp} @var{mode-function}
-@var{flag})} and @var{flag} is non-@code{nil}, then after calling
-@var{mode-function}, Emacs discards the suffix that matched
-@var{regexp} and searches the list again for another match.
-@vindex auto-mode-case-fold
-  On systems with case-insensitive file names, such as Microsoft
-Windows, Emacs performs a single case-insensitive search through
-@code{auto-mode-alist}.  On other systems, Emacs normally performs a
-single case-sensitive search through the alist.  However, if you
-change the variable @code{auto-mode-case-fold} to @code{t}, Emacs
-performs a second case-insensitive search if the first search fails.
-@vindex magic-fallback-mode-alist
-  Finally, if Emacs @emph{still} hasn't found a major mode to use, it
-compares the text at the start of the buffer to the variable
-@code{magic-fallback-mode-alist}.  This variable works like
-@code{magic-mode-alist}, described above, except that is consulted
-only after @code{auto-mode-alist}.  By default,
-@code{magic-fallback-mode-alist} contains forms that check for image
-files, HTML/XML/SGML files, and Postscript files.
-@vindex major-mode
-  Once a major mode is chosen, Emacs sets the value of the variable
-@code{major-mode} to the symbol for that major mode (e.g.,
-@code{text-mode} for Text mode).  This is a per-buffer variable
-(@pxref{Locals}); its buffer-local value is set automatically, and you
-should not change it yourself.
-  The default value of @code{major-mode} determines the major mode to
-use for files that do not specify a major mode, and for new buffers
-created with @kbd{C-x b}.  Normally, this default value is the symbol
-@code{fundamental-mode}, which specifies Fundamental mode.  You can
-change it via the Customization interface (@pxref{Easy
-Customization}), or by adding a line like this to your init file
-(@pxref{Init File}):
-@smallexample
-(setq-default major-mode 'text-mode)
-@end smallexample
-@noindent
-If the default value of @code{major-mode} is @code{nil}, the major
-mode is taken from the previously current buffer.
-@findex normal-mode
-  If you have changed the major mode of a buffer, you can return to
-the major mode Emacs would have chosen automatically, by typing
-@kbd{M-x normal-mode}.  This is the same function that
-@code{find-file} calls to choose the major mode.  It also processes
-the file's @samp{-*-} line or local variables list (if any).
-@xref{File Variables}.
-@vindex change-major-mode-with-file-name
-  The commands @kbd{C-x C-w} and @code{set-visited-file-name} change to
-a new major mode if the new file name implies a mode (@pxref{Saving}).
-(@kbd{C-x C-s} does this too, if the buffer wasn't visiting a file.)
-However, this does not happen if the buffer contents specify a major
-mode, and certain ``special'' major modes do not allow the mode to
-change.  You can turn off this mode-changing feature by setting
-@code{change-major-mode-with-file-name} to @code{nil}.

+  Major modes provide specialized facilities for working on a
+particular file type, such as a C source file (@pxref{Programs}), or a
+particular type of non-file buffer, such as a shell buffer
+(@pxref{Shell}).  Major modes are mutually exclusive; each buffer has

+@section Minor Modes
+@cindex minor modes
+@cindex mode, minor
+  A minor mode is an optional editing modes that alters the behavior
+of Emacs in some well-defined way.  Unlike major modes, any number of
+minor modes can be in effect at any time.  Some minor modes are
+@dfn{buffer-local}: they apply only to the current buffer, so you can
+enable the mode in certain buffers and not others.  Other minor modes
+are @dfn{global}: while enabled, they affect everything you do in the
+Emacs session, in all buffers.  Some global minor modes are enabled by
+default.
+  Most minor modes say in the mode line when they are enabled, just
+after the major mode indicator.  For example, @samp{Fill} in the mode
+line means that Auto Fill mode is enabled.  @xref{Mode Line}.
+  Each minor mode is associated with a command, called the @dfn{mode
+command}, which turns it on or off.  The name of this command consists
+of the name of the minor mode, followed by @samp{-mode}; for instance,
+the mode command for Auto Fill mode is @code{auto-fill-mode}.  Calling
+the minor mode command with no prefix argument @dfn{toggles} the mode,
+turning it on if it was off, and off if it was on.  A positive
+argument always turns the mode on, and a zero or negative argument
+always turns it off.  Mode commands are usually invoked with
+@kbd{M-x}, but you can bind keys to them if you wish (@pxref{Key
+Bindings}).
+  Most minor modes also have a @dfn{mode variable}, with the same name
+as the mode command.  Its value is non-@code{nil} if the mode is
+enabled, and @code{nil} if it is disabled.  In some minor modes---but
+not all---the value of the variable alone determines whether the mode
+is active: the mode command works simply by setting the variable, and
+changing the value of the variable has the same effect as calling the
+mode command.  Because not all minor modes work this way, we recommend
+that you avoid changing the mode variables directly; use the mode
+commands instead.

+front of the @samp{B} in @samp{FOOBAR}, then in Overwrite mode typing
+a @kbd{G} changes it to @samp{FOOGAR}, instead of producing
+@samp{FOOGBAR} as usual.  In Overwrite mode, the command @kbd{C-q}
+inserts the next character whatever it may be, even if it is a
+digit---this gives you a way to insert a character instead of
+replacing an existing character.  The mode command,
+@code{overwrite-mode}, is bound to the @key{Insert} key.
+@findex binary-overwrite-mode
+@item
+Binary Overwrite mode is a variant of Overwrite mode for editing
+binary files; it treats newlines and tabs like other characters, so
+that they overwrite other characters and can be overwritten by them.
+In Binary Overwrite mode, digits after @kbd{C-q} specify an octal

+@node Choosing Modes
+@section Choosing File Modes
+@cindex choosing a major mode
+@cindex choosing a minor mode
+@vindex auto-mode-alist
+  When you visit a file, Emacs chooses a major mode automatically.
+Normally, it makes the choice based on the file name---for example,
+files whose names end in @samp{.c} are normally edited in C mode---but
+sometimes it chooses the major mode based on special text in the file.
+This special text can also be used to enable buffer-local minor modes.
+  Here is the exact procedure:
+  First, Emacs checks whether the file contains file-local mode
+variables.  @xref{File Variables}.  If there is a file-local variable
+that specifies a major mode, then Emacs uses that major mode, ignoring
+all other criteria.  There are several methods to specify a major mode
+using a file-local variable; the simplest is to put the mode name in
+the first nonblank line, preceded and followed by @samp{-*-}.  Other
+text may appear on the line as well.  For example,
+@example
+; -*-Lisp-*-
+@end example
+@noindent
+tells Emacs to use Lisp mode.  Note how the semicolon is used to make
+Lisp treat this line as a comment.  Alternatively, you could write
+@example
+; -*- mode: Lisp;-*-
+@end example
+@noindent
+The latter format allows you to specify local variables as well, like
+this:
+@example
+; -*- mode: Lisp; tab-width: 4; -*-
+@end example
+  If a file variable specifies a buffer-local minor mode, Emacs
+enables that minor mode in the buffer.
+@vindex interpreter-mode-alist
+  Second, if there is no file variable specifying a major mode, Emacs
+checks whether the file's contents begin with @samp{#!}.  If so, that
+indicates that the file can serve as an executable shell command,
+which works by running an interpreter named on the file's first line
+(the rest of the file is used as input to the interpreter).
+Therefore, Emacs tries to use the interpreter name to choose a mode.
+For instance, a file that begins with @samp{#!/usr/bin/perl} is opened
+in Perl mode.  The variable @code{interpreter-mode-alist} specifies
+the correspondence between interpreter program names and major modes.
+  When the first line starts with @samp{#!}, you usually cannot use
+the @samp{-*-} feature on the first line, because the system would get
+confused when running the interpreter.  So Emacs looks for @samp{-*-}
+on the second line in such files as well as on the first line.  The
+same is true for man pages which start with the magic string
+@samp{'\"} to specify a list of troff preprocessors.
+@vindex magic-mode-alist
+  Third, Emacs tries to determine the major mode by looking at the
+text at the start of the buffer, based on the variable
+@code{magic-mode-alist}.  By default, this variable is @code{nil} (an
+empty list), so Emacs skips this step; however, you can customize it
+in your init file (@pxref{Init File}).  The value should be a list of
+elements of the form
+@example
+(@var{regexp} . @var{mode-function})
+@end example
+@noindent
+where @var{regexp} is a regular expression (@pxref{Regexps}), and
+@var{mode-function} is a Lisp function that toggles a major mode.  If
+the text at the beginning of the file matches @var{regexp}, Emacs
+chooses the major mode specified by @var{mode-function}.
+Alternatively, an element of @code{magic-mode-alist} may have the form
+@example
+(@var{match-function} . @var{mode-function})
+@end example
+@noindent
+where @var{match-function} is a Lisp function that is called at the
+beginning of the buffer; if the function returns non-@code{nil}, Emacs
+set the major mode wit @var{mode-function}.
+  Fourth---if Emacs still hasn't found a suitable major mode---it
+looks at the file's name.  The correspondence between file names and
+major modes is controlled by the variable @code{auto-mode-alist}.  Its
+value is a list in which each element has this form,
+@example
+(@var{regexp} . @var{mode-function})
+@end example
+@noindent
+or this form,
+@example
+(@var{regexp} @var{mode-function} @var{flag})
+@end example
+@noindent
+For example, one element normally found in the list has the form
+@code{(@t{"\\.c\\'"} . c-mode)}, and it is responsible for selecting C
+mode for files whose names end in @file{.c}.  (Note that @samp{\\} is
+needed in Lisp syntax to include a @samp{\} in the string, which must
+be used to suppress the special meaning of @samp{.} in regexps.)  If
+the element has the form @code{(@var{regexp} @var{mode-function}
+@var{flag})} and @var{flag} is non-@code{nil}, then after calling
+@var{mode-function}, Emacs discards the suffix that matched
+@var{regexp} and searches the list again for another match.
+@vindex auto-mode-case-fold
+  On systems with case-insensitive file names, such as Microsoft
+Windows, Emacs performs a single case-insensitive search through
+@code{auto-mode-alist}.  On other systems, Emacs normally performs a
+single case-sensitive search through the alist.  However, if you
+change the variable @code{auto-mode-case-fold} to @code{t}, Emacs
+performs a second case-insensitive search if the first search fails.
+@vindex magic-fallback-mode-alist
+  Finally, if Emacs @emph{still} hasn't found a major mode to use, it
+compares the text at the start of the buffer to the variable
+@code{magic-fallback-mode-alist}.  This variable works like
+@code{magic-mode-alist}, described above, except that is consulted
+only after @code{auto-mode-alist}.  By default,
+@code{magic-fallback-mode-alist} contains forms that check for image
+files, HTML/XML/SGML files, and Postscript files.
+@vindex major-mode
+  Once a major mode is chosen, Emacs sets the value of the variable
+@code{major-mode} to the symbol for that major mode (e.g.,
+@code{text-mode} for Text mode).  This is a per-buffer variable
+(@pxref{Locals}); its buffer-local value is set automatically, and you
+should not change it yourself.
+  The default value of @code{major-mode} determines the major mode to
+use for files that do not specify a major mode, and for new buffers
+created with @kbd{C-x b}.  Normally, this default value is the symbol
+@code{fundamental-mode}, which specifies Fundamental mode.  You can
+change it via the Customization interface (@pxref{Easy
+Customization}), or by adding a line like this to your init file
+(@pxref{Init File}):
+@smallexample
+(setq-default major-mode 'text-mode)
+@end smallexample
+@noindent
+If the default value of @code{major-mode} is @code{nil}, the major
+mode is taken from the previously current buffer.
+@findex normal-mode
+  If you have changed the major mode of a buffer, you can return to
+the major mode Emacs would have chosen automatically, by typing
+@kbd{M-x normal-mode}.  This is the same function that
+@code{find-file} calls to choose the major mode.  It also processes
+the file's @samp{-*-} line or local variables list (if any).
+@xref{File Variables}.
+@vindex change-major-mode-with-file-name
+  The commands @kbd{C-x C-w} and @code{set-visited-file-name} change to
+a new major mode if the new file name implies a mode (@pxref{Saving}).
+(@kbd{C-x C-s} does this too, if the buffer wasn't visiting a file.)
+However, this does not happen if the buffer contents specify a major
+mode, and certain ``special'' major modes do not allow the mode to
+change.  You can turn off this mode-changing feature by setting
+@code{change-major-mode-with-file-name} to @code{nil}.

-  Sometimes, you may come across ``unfilled'' text files, which Emacs
-normally displays as a bunch of extremely long lines.  Comfortably
-reading and editing such files normally requires ``word wrap'', a
-feature that breaks up each long text line into multiple screen lines
-in a readable manner---by putting the breaks at word boundaries.  Many
-text editors, such as those built into many web browsers, perform word
-wrapping by default.
-  There are two different minor modes in Emacs that perform word
-wrapping.  The first is Visual Line mode, which does it by altering
-the behavior of screen line continuation.  @xref{Visual Line Mode},
-for information about Visual Line mode.
-@findex longlines-mode
-  Instead of using Visual Line mode, you can use a minor mode called
-Long Lines mode.  Long Lines mode wraps lines by inserting or deleting
-@dfn{soft newlines} as you type (@pxref{Hard and Soft Newlines}).
-These soft newlines won't show up when you save the buffer into a
-file, or when you copy the text into the kill ring, clipboard, or a
-register.  Unlike Visual Line mode, Lone Lines mode breaks long lines
-at the fill column (@pxref{Fill Commands}), rather than the right
-window edge.  To enable Long Lines mode, type @kbd{M-x
-longlines-mode}.  If the text is full of long lines, this also
-immediately ``wraps'' them all.
-@findex longlines-auto-wrap
-  The word wrap performed by Long Lines mode is @emph{not} the same as
-ordinary filling (@pxref{Fill Commands}).  It does not contract
-multiple spaces into a single space, recognize fill prefixes
-(@pxref{Fill Prefix}), or perform adaptive filling (@pxref{Adaptive
-Fill}).  The reason for this is that a wrapped line is still,
-conceptually, a single line.  Each soft newline is equivalent to
-exactly one space in that long line, and vice versa.  However, you can
-still call filling functions such as @kbd{M-q}, and these will work as
-expected, inserting soft newlines that won't show up on disk or when
-the text is copied.  You can even rely entirely on the normal fill
-commands by turning off automatic line wrapping, with @kbd{C-u M-x
-longlines-auto-wrap}.  To turn automatic line wrapping back on, type
-@kbd{M-x longlines-auto-wrap}.
-@findex longlines-show-hard-newlines
-  Type @kbd{RET} to insert a hard newline, one which automatic
-refilling will not remove.  If you want to see where all the hard
-newlines are, type @kbd{M-x longlines-show-hard-newlines}.  This will
-mark each hard newline with a special symbol.  The same command with a
-prefix argument turns this display off.
-  Long Lines mode does not change normal text files that are already
-filled, since the existing newlines are considered hard newlines.
-Before Long Lines can do anything, you need to transform each
-paragraph into a long line.  One way is to set @code{fill-column} to a
-large number (e.g., @kbd{C-u 9999 C-x f}), re-fill all the paragraphs,
-and then set @code{fill-column} back to its original value.
