Use actual spaces to align completion annotations instead of
"specified space" display properties, since that allows
'completion--insert-strings' to correctly align multiple completion
columns when 'completions-format' is not 'one-column'.
* lisp/minibuffer.el (completion-styles-affixation)
(completion-file-name-affixation): Align annotations with spaces
instead of using '(space :align-to ...)' display properties.
(minibuffer--sort-file-names-by-last-modified-time): New function.
(read-file-name-default): Add it to
'minibuffer-completions-sort-orders' buffer-locally.
* doc/emacs/mini.texi (Completion Commands): Elaborate about
'minibuffer-sort-completions'.
* lisp/minibuffer.el (completion-file-name-affixation): New function.

from here to...
* doc/emacs/mini.texi (Completion Options): ...here. Improve wording.
* etc/NEWS: Announce.
Extend 'completions-header-format' with a placeholder for the
completions category. Stop hard-coding the 'shadow' face for the
heading line default value, instead define a derived face.
* lisp/minibuffer.el (completions-header-format): Extend.
(completions-heading): New face.
(completion-category): New variable.
(minibuffer-completion-help): Let-bind it.
(display-completion-list): Use it.
* doc/emacs/mini.texi (Completion Options): Elaborate.
* etc/NEWS: Announce.
* lisp/minibuffer.el (minibuffer--cache-completion-input): Accept the
minibuffer base contents, not just its length.

is up to date before restoring.

(minibuffer-completion-help): Adapt.
Add an interactive command for setting completion styles in the
current minibuffer.

(completion--styles): Use 'completion-local-styles' when it's non-nil.
(completion--nth-completion): Set 'completion--matching-style' to the
matching completion style.
(completion-styles-affixation, completion-styles-table): New funs.
(minibuffer-set-completion-styles): New command.

(completions-multi-mode): Use it instead of 'crm-separator'.
(completing-read-multiple): Let-bind 'crm-current-separator' to the
current value of 'crm-separator'.
* lisp/menu-bar.el (minibuffer-local-completion-map): Bind
'minibuffer-complete-and-exit' in "Minibuf" menu bar menu, shadowing
the binding of 'exit-minibuffer' in that menu.
This simplifies the implementation of crm.el, making it a thin wrapper
around 'completing-read'. This obviates the need for bespoke commands
such as 'crm-complete' and 'crm-completion-help', and allows us to
remove incorrect code in minibuffer.el that tried to accommodate for
both 'completing-read' and 'completing-read-multiple'.
'crm-complete-and-exit' is still required to get the right behavior.
While we're at it, also add a command for changing 'crm-separator'
interactively, and an indication of 'completing-read-multiple' in
the *Completions* buffer mode line.
* lisp/emacs-lisp/crm.el (crm-local-completion-map)
(crm-local-must-match-map): No longer used, replace with obsolete
aliases of 'completing-read-multiple-mode-map' in favor of third party
code that uses these variables.

a pair of buffer positions in the minibuffer.
(minibuffer--add-completions-predicate)

(minibuffer-narrow-completions-to-current): Use it.
This adds a new global minor that updates the *Completions* buffer as
you type in the minibuffer.

* doc/lispref/minibuf.texi (Completion Commands):
(Programmed Completion): Update documenation.
* etc/NEWS: Announce new feature.
* lisp/emacs-lisp/derived.el (define-derived-mode): Use a reference
to the mode symbol instead of the mode's "pretty" name in
the hook variable's docstring.
* src/lisp.h (make_lisp_symbol): In eassert use XBARE_SYMBOL
rather than XSYMBOL. This is safe because the symbol must be
bare. The change speeds up make_lisp_symbol when debugging.
* src/lisp.h (XSYMBOL): Simplify and tune. There is no need to
examine symbols_with_pos_enabled here, since the arg must be a symbol
so if it's not a bare symbol then it must be a symbol_with_pos;
and checking whether a symbol is bare is cheap.
With Ubuntu 23.10 on a Xeon W-1350, this shrank Emacs’s executable
text size by 0.1% and sped up a default build of all *.elc files by
0.4%.
Remove unnecessary eassert, since XBARE_SYMBOL and XSYMBOL_WITH_POS
have easserts that suffice.
Be more systematic about putting space before paren in calls,
and in avoiding unnecessary parentheses in macros.
This was partly inspired by my wading through gcc -E output
while debugging something else, and seeing too many parens.
This patch does not change the generated .o files on my platform.
* src/lisp.h (XBARE_SYMBOL, XSYMBOL): Omit parentheses that are no
longer needed now that we have symbols with positions and these
symbols are never macros.
Problem reported by Gerd Möllmann (Bug#68464).
* .gitignore: Ignore files in exec that are now copied from build-aux.
* admin/merge-gnulib (avoided_flags): Instead of clearing
autom4te.cache here ...
* autogen.sh (do_git): ... clear it here.
Use config.guess, config.sub and install-sh from
the Emacs repository, as they are more likely to be up to date.
This avoids unnecessary differences among different builders,
and avoids unnecessary ‘git diff’ output after autogen.sh.
Also, copy these files from build-aux to exec since there
should be no difference between the two copies.
* exec/config.guess, exec/config.sub, exec/install-sh:
Remove from repository, as autogen.sh now copies them from build-aux.
