* src/xdisp.c (syms_of_xdisp) <nobreak-char-ascii-display>: New
variable.
(get_next_display_element): If 'nobreak-char-ascii-display' is
non-nil, display non-ASCII space and hyphen characters as their
ASCII equivalents. (Bug#50983)
* etc/NEWS:
* etc/PROBLEMS: Mention 'nobreak-char-ascii-display'.
* nt/gnulib-cfg.mk (OMIT_GNULIB_MODULE_free-posix)
(OMIT_GNULIB_MODULE_malloc-posix)
(OMIT_GNULIB_MODULE_realloc-gnu)
(OMIT_GNULIB_MODULE_realloc-posix):
New macros, since we don’t want these modules on MS-Windows.
* src/w32heap.c (heap_alloc, heap_realloc): New functions.
(malloc_after_dump, realloc_after_dump, realloc_before_dump):
Use them.
Make the following changes by hand, and run 'admin/merge-gnulib'.
* .gitignore: Add lib/malloc/*.gl.h.
* admin/merge-gnulib: Copy lib/af_alg.h and lib/save-cwd.h
directly from Gnulib, without worrying about Gnulib modules,
as these files are special cases.
(AVOIDED_MODULES): Remove malloc-posix.
* lib/malloc.c, lib/realloc.c, m4/malloc.m4, m4/realloc.m4:
* m4/year2038.m4: New files, copied from Gnulib.
* lib/malloca.c, lib/malloca.h:
* m4/close-stream.m4, m4/glibc21.m4, m4/malloca.m4:
Remove. These are either no longer present in Gnulib, or are no
longer needed by modules that Emacs uses.
* oldXMenu/AddPane.c, oldXmenu/Addsel.c: Include XmenuInt.h first;
needed for new Gnulib.
* src/xmenu.c: Call emacs_abort, not abort.
* src/xmenu.c (x_menu_show): Explicitly check whether save_wv can
be null here. Looks like it can be but I am not 100% sure, so
play it safe and add a FIXME comment.
* src/xterm.c (x_connection_closed): Don’t dereference dpyinfo
in the unlikely case where it is null and ioerror is true.
This pacifies gcc 11.2.1 -Wanalyzer-null-dereference.
* src/xfns.c (x_hide_tip, Fx_show_tip): Be consistent about using
!NILP (tip_frame) instead of FRAMEP (tip_frame). The two
expressions are logically equivalent since tip_frame is either a
frame or nil, !NILP is a bit faster, and making things consistent
pacifies gcc 11.2.1 -Wanalyzer-null-dereference.
* src/term.c (encode_terminal_code): Clarify by removing a couple
of UNINITs and testing the local variable ‘cmp’ instead of
retesting src->u.cmp.automatic. This pacifies gcc 11.2.1
-Wanalyzer-null-dereference.
* src/systhread.h: Put NODISCARD at the start of extern
declarations, not at the end. This is needed by C2x.
This patch also pacifies gcc 11.2.1 -Wattributes.
* src/alloc.c (lisp_malloc): Document that NBYTES must be
positive, and omit a needless runtime check. This pacifies a
false alarm with gcc 11.2.1 -Wanalyzer-possible-null-dereference.
The new name fits better in the family of variables that affect
the Lisp reader.

created, and run the toolbar update immediately.
If the codepoint that triggered composition is from the emoji script,
use the emoji font to check the string being composed, rather than the
font of the first character of the string. This makes e.g.
"emoji codepoint with Emoji_Presentation = No followed by VS-16 (FE0F)"
display the emoji version of the glyph for that codepoint.

that triggered composition to autocmp_chars.

triggering codepoint. If the codepoint is from the 'emoji' script,
use Vscript_representative_chars to find the font to use for the
composition attempt.
(syms_of_font): Add Qemoji symbol.
* src/font.h: Update font_range prototype for argument CH.
* etc/NEWS: Announce change.
* src/lread.c (oblookup_considering_shorthand): Now static. Move
prototype to where it belongs.
(read1, Fintern, Fintern_soft, Funintern)
(oblookup_considering_shorthand, syms_of_lread): Fix style of
braces and indentation, comments, and doc strings.
Instead of referencing obarray directly, that function has to consider
a collection of completions which includes the shorthand versions of
some of the symbols. That collection changes from buffer to buffer,
depending on the choice of elisp-shorthands.
To make this process efficient, and avoid needless recalculation of
the above collection, a new obarray-specific cache was invented. The
Elisp variable obarray-cache is immediately nullified if something
touches the obarray.
* lisp/progmodes/elisp-mode.el : New helper.
(elisp-completion-at-point): Use new helpers.
(elisp--completion-local-symbols)
(elisp--fboundp-considering-shorthands)
(elisp--bboundp-considering-shorthands): New helpers
* src/lread.c (intern_driver): Nullify Qobarray_cache.

(elisp-shorthand-completion-at-point): New test.
* test/lisp/progmodes/elisp-resources/simple-shorthand-test.el
(f-test-complete-me): New fixture.
This simplification in requirements makes for more complex C code but
that code is much less wasteful in Lisp strings than the previous
implementation.
* src/lread.c (read1): Rework.
(Fintern): Rework.
(Fintern_soft): Rework.
(Funintern): Rework.
(oblookup_considering_shorthand): Rewrite.
* test/lisp/progmodes/elisp-mode-tests.el (elisp-shorthand-read-buffer)
(elisp-shorthand-read-from-string): Use new format of
elisp-shorthands.
* test/lisp/progmodes/elisp-resources/simple-shorthand-test.el (f-test)
(f-test2, f-test3): Use new form of elisp-shorthands.
It passes the tests designed for the previous Elisp implementation.
Likely, this isn't the final form of the implementation. For one, the
reader is much slower and allocates a Lisp string for every atom read,
regardless if its already interned or not. This has the potential to
be catastrophic in terms of GC.
Also rename the main variable to elisp-shorthands, from the
repetitive shorthand-shorthands.
For some reason, I had to put 'hack-elisp-shorthands' and
'load-with-shorthands-and-code-conversion', the new source-file
loading functions, in lisp/international/mule.el.
Otherwise, lisp/loadup.el wouldn't see them, for some reason that I
didn't investigate. This should probably be fixed.
* lisp/shorthand.el: Remove.
* test/lisp/shorthand-tests.el: Remove.
* src/lread.c:

very useful, and it never worked properly. Disallow it.

Signal error for &rest without variable name.

* src/character.h: Add TAG_SPACE and CANCEL_TAG to known Unicode
characters values.
* src/composite.c (char_composable_p): Recognize TAG characters
relevant to Emoji as composable regardless of their General
Category. (Bug#39799)

actually literal) common case.
