* src/xdisp.c (get_next_display_element): For a composition on a
display or overlay string, set the end_of_box_run_p flag if the
string ends at the last character included in the composition.
(fill_gstring_glyph_string): Fix the way the width of a gstring
glyph string is calculated: use the values calculated in
gui_produce_glyphs, since the latter adjusts the width due to the
face's ':box' attribute.
* src/xterm.c (x_draw_glyph_string_box):
* src/w32term.c (w32_draw_glyph_string_box):
* src/nsterm.m (ns_dumpglyphs_box_or_relief): Support automatic
compositions, which have the right_box_line_p flag set on the last
glyph produced from the composition. (Bug#40687)
* src/w32term.c (w32_compute_glyph_string_overhangs): Update to be
consistent with xterm.c in its support of automatic composition
glyph strings.
* src/dispextern.h (enum glyph_type): More accurate commentary.
* src/.gdbinit (pgx): Display slice.img members only for image
glyphs.
* src/keymap.c (push_text_char_description): Omit useless code.
(Ftext_char_description): Minor code cleanup, inspired by
seeing an incorrect comment about MAX_MULTIBYTE_LENGTH’s value.
* src/character.c (parse_str_as_multibyte, str_as_multibyte):
Let the fast loop run a little longer, fixing what appears
to be an off-by-1 performance nit.
* src/character.h (MULTIBYTE_LENGTH, MULTIBYTE_LENGTH_NO_CHECK):
Remove, replacing with ...
(multibyte_length): ... this new function. All callers changed.
The new function rejects overlong multibyte forms.
* test/src/buffer-tests.el (buffer-multibyte-overlong-sequences):
New test.
* src/w32image.c (w32_load_image): Remove a workaround for a bug
that is not needed anymore. This error was happening because
GDI+ functions were called as CDECL, not as STDCALL.
* lisp/image-mode.el (image-mode-map): Regroup existing keybindings and
add new ones with the prefix key 's'.
Remove condition ":visible (eq image-type 'imagemagick)" from menu.
(image-toggle-display-image): Don't rotate again after user rotated manually.
(image-transform-check-size): Remove check for imagemagick.
(image-transform-properties, image-transform-set-scale)
(image-transform-fit-to-height, image-transform-fit-to-width)
(image-transform-set-rotation, image-transform-reset):
Remove mentions of ImageMagick from docstrings since these commands
now work without ImageMagick.
* doc/emacs/windows.texi (Window Convenience): Add descriptions of
windmove-display-default-keybindings,
windmove-delete-default-keybindings,
windmove-swap-states-in-direction.
* etc/NEWS: Regroup to move some parts closer to related sections.
See Bug#40693#32.
* doc/lispref/eval.texi (Self-Evaluating Forms, Backquote):
Say that these yield constant conses, vectors and strings,
not constant symbols.
* doc/lispref/objects.texi (Constants and Mutability): Say that an
attempt to modify a constant variable signals an error, instead of
saying that it has undefined behavior.
This change was inspired by comments from Štěpán Němec in:
https://lists.gnu.org/r/emacs-devel/2020-04/msg01063.html
* doc/lispref/objects.texi (Lisp Data Types): Mention mutability.
(Constants and mutability): New section.
* doc/lispintro/emacs-lisp-intro.texi (Lists diagrammed)
(Indent Tabs Mode): Improve wording.
* doc/lispref/eval.texi (Self-Evaluating Forms):
Say that they return constants.
* doc/lispref/lists.texi (Sets And Lists):
Fix memql mistake/confusion that I recently introduced.
* src/w32image.c: Define correct WINGDIPAPI typedefs for GDI+
functions. We cannot use DEF_DLL_FN, since that is for functions
with C calling conventions, whereas GDI+ functions are __stdcall.
(gdiplus_init): Load functions from DLL manually, not via
LOAD_DLL_FN, as the latter is for __cdecl functions.
(w32_frame_delay): Initialize delay with a negative value, as zero
is a valid delay.
This is a preventive change, since Gnulib was recently changed
its explicit_bzero to call SecureZeroMemory on MS-Windows,
disregarding systems older than XP, which didn't have it.
* src/w32.c (explicit_bzero): New function.
* nt/mingw-cfg.site (ac_cv_func_explicit_bzero): Avoid using the
Gnulib replacement for explicit_bzero.
* nt/inc/ms-w32.h (explicit_bzero): Add prototype.
* doc/lispref/abbrevs.texi (Abbrev Expansion):
* doc/lispref/backups.texi (Reverting):
* doc/lispref/functions.texi (Mapping Functions):
* doc/lispref/help.texi (Accessing Documentation):
* doc/lispref/sequences.texi (Char-Tables):
* doc/lispref/syntax.texi (Categories):
* doc/lispref/text.texi (Sorting):
Remove function quoting from lambda in examples where it still occurs,
since examples should follow our best style and be consistent.
* lisp/elide-head.el: Use lexical-binding.
(elide-head-headers-to-hide): Remove redundant :group arg.
(elide-head-overlay): Use `defvar-local'.
(elide-head-show): Fix docstring.
* test/lisp/elide-head-tests.el: New file with tests for
elide-head.el.
This patch builds on a suggested patch by Mattias Engdegård
and on further comments by Eli Zaretskii.
Original bug report by Kevin Vigouroux (Bug#40671).

* lisp/apropos.el: Use lexical-binding and remove redundant
:group args.
(apropos-words-to-regexp, apropos): Tweak docstrings.
(apropos-value-internal): Replace '(if x (progn y))' with
'(when x y)'.
(apropos-format-plist): Add docstring and replace '(if x (progn y))'
with '(when x y)'.
* test/lisp/apropos-tests.el: New file with tests for apropos.el.
I was at a loss as to why my attempt to set up spam-stat seemed to
have no effect, only to find (digging in the code) that it was
ignoring most of the sample files due to this undocumented variable.
* doc/misc/gnus.texi (Creating a spam-stat dictionary): Document
the variable 'spam-stat-process-directory-age'. (bug#39780)

* src/w32image.c (w32_frame_delay): Don't try to compute frame
delay if GdipGetPropertyItemSize fails for PropertyTagFrameDelay.
(w32_load_image): Don't add 'delay' member to metadata if the
delay could not be determined.

doc string.

or tab bars.
* src/fns.c (mapcar1):
* src/keymap.c (Fkey_description):
* src/syntax.c (scan_lists):
Prefer ptrdiff_t to EMACS_INT where either will do; this fixes
newly-introduced type errors on --with-wide-int platforms where
ptrdiff_t is narrower than EMACS_INT.
* src/keymap.c (Fkey_description): Rework for clarity; remove goto.
* src/syntax.c (scan_words, Fforward_comment, scan_lists)):
Fix unlikely integer overflow problems that can occur on
--with-wide-int platforms, and that were caught by the recent
character.h changes.
