* identity, ignore: Make arg names more consistent with docsJuanma Barranquero2019-10-101-3/+3
| | | | | | | | * lisp/subr.el (ignore): Rename argument IGNORE to ARGUMENTS. * src/fns.c (Fidentity): Rename ARG to ARGUMENT. * doc/lispref/functions.texi (Calling Functions): Fix references.
* Silence compiler warningJuanma Barranquero2019-10-091-1/+1
| | | | * src/w32.c (acl_to_text): Add ATTRIBUTE_MALLOC.
* Implement offsets for absolute line numbersJuanma Barranquero2019-10-091-7/+36
| | | | | | | | | | | | | | * src/xdisp.c (syms_of_xdisp) <display-line-numbers-offset>: New variable to add an offset to absolute line numbers. (syms_of_xdisp) <display-line-numbers>: Mention it in docstring. (maybe_produce_line_number): Use it. * doc/emacs/display.texi (Display Custom): Document it. * etc/NEWS (value): Announce it. * lisp/frame.el: Add `display-line-numbers-offset' to list of variables which should trigger redisplay of the current buffer.
* Do not use tick faces beyond ZV (bug#37641)Juanma Barranquero2019-10-091-17/+21
| | | | | | * src/xdisp.c (maybe_produce_line_number): Check beyond_zv before using a tick face for the line number. Move all face selection code outside the loop that draws the line number.
* Make add-face-text-property not be destructive on stringsLars Ingebrigtsen2019-10-091-9/+23
| | | | | | | | | | * src/textprop.c (add_properties): Take a parameter to say whether it's allowed to be destructive or not (bug#20153). (add_text_properties_1): Ditto. (Fadd_face_text_property): Use this to say that it shouldn't modify face properties on strings destructively. This avoids altering the face properties of one string when altering them on a copy of the string.
* Fix crashes on TTY frames due to "C-x 6 f"Eli Zaretskii2019-10-082-2/+14
| | | | | | | | | | | * src/xdisp.c (redisplay_internal): Revert the recent change regarding TTY frames' garbaged flag. It is not needed. * src/dispnew.c (adjust_frame_glyphs_for_frame_redisplay): When returning due to mismatch between the desired and actual dimensions of the glyph matrix, set the frame's garbaged flag for TTY frames. This avoids crashes when we are later called from redisplay. Reported by Ergus <spacibba@aol.com>.

* Fix infloop in redisplay caused by a recent changeEli Zaretskii2019-10-071-1/+5
| | | | | | * src/xdisp.c (redisplay_internal): Avoid inflooping due to a frame's garbaged flag being set after update_frame. Reported by Michael Heerdegen <michael_heerdegen@web.de>.
* Feval_buffer doc string lexical-binding clarificationLars Ingebrigtsen2019-10-071-0/+6
| | | | | * src/lread.c (Feval_buffer): Mention that the lexical-binding variable is ignored in the doc string (bug#20139).
* Fix port of file-acl errno checking to non-GNUPaul Eggert2019-10-061-1/+1
| | | | | | I had misinterpreted the private email from Ashish Shukla. * src/fileio.c (Ffile_acl): Fix typo in previous change by negating the call to acl_errno_valid.
* Fix the colours on Motif horizontal scroll barsLars Ingebrigtsen2019-10-071-2/+4
| | | | | | * src/xterm.c (x_create_horizontal_toolkit_scroll_bar): Use the same foreground/background colours as the vertical scroll bar (bug#37359).
* Allow using last_tab_bar_item on no-x builds.Juri Linkov2019-10-071-2/+0

(syms_of_xdisp) <line-number-major-tick, line-number-minor-tick>: Defsym new faces. (maybe_produce_line_number): Use new faces for line numbers that are multiple of `display-line-numbers-major-tick' and `display-line-numbers-minor-tick'. * etc/NEWS (value): Announce new feature. * doc/emacs/display.texi (Display Custom): Describe it.
