* etc/NEWS: Mention the change.
* lisp/vc/vc.el (vc-switch-backend): Mark as obsolete (bug#50344).
(vc-transfer-file): Wrap the calls in 'with-suppressed-warnings'.
* lisp/image-dired.el (image-dired-thumb-file-marked-p): Don't
move point in associated dired buffer.
(image-dired-delete-marked): Revert "Fix deletion of associated image"
because it was wrong and introduced another problem (bug#51152).
bug#51089
1. The 'punctuation' syntax class is actually empty in Emacs Lisp.
The class used in the implementation is 'symbol constituents';
2) The prefix to escape shorthands is '#_' together, not '#' or '_'.
* doc/lispref/symbols.texi (Shorthands): Fix exception.
* src/lread.c (read1): Minor stylistic fixes of the last change,
including the wording of the comment.
* doc/lispref/symbols.texi (Shorthands): Fix wording and typos.
This includes symbols used for arithmetic functions such as -, /=,
etc. Using "-" or "/=" is still possible but doing so won't shadow
those functions.
* doc/lispref/symbols.texi (Shorthand, Exceptions): New
subsubsection.
* src/lread.c (read1): Exempt punctionation-only symbols from
oblookup_considering_shorthand.
* test/lisp/progmodes/elisp-mode-tests.el
(elisp-dont-shadow-punctuation-only-symbols): Tweak test.
This change was first made on master, but on closer consideration it
is better to fix this bug already in Emacs 28.1.
* lisp/progmodes/python.el (python-font-lock-keywords-level-2):
Fontify "print" and "exec" as functions, which is the case in
Python 3. (Bug#43298) Do not merge to master.
* lisp/tab-line.el (tab-line-tab-current): Don't inherit face from
'tab-line-tab' to not inherit the face attribute :height from 'tab-line',
because :height of mouse-face is added to the base face.
Copy here most of the parent face attributes (bug#50798).
This addresses a FIXME comment in lisp/emacs-lisp/comp.el,
relating to the number of subsidiary processes used by
comp-run-async-workers in native compilation.
* admin/merge-gnulib (GNULIB_MODULES): Add nproc.
* doc/lispref/processes.texi (Process Information), etc/NEWS:
Document num-processors.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* lib/nproc.c, lib/nproc.h, m4/nproc.m4:
New files, copied from Gnulib by admin/merge-gnulib.
* lisp/emacs-lisp/comp.el (w32-get-nproc): Remove decl.
(comp-effective-async-max-jobs): Use num-processors.
* src/process.c: Include nproc.h.
(Fnum_processors): New function.
(syms_of_process): Define ‘all’, ‘current’, ‘num-processors’.
* src/w32proc.c (Fw32_get_nproc): Add FIXME comment.
* test/src/process-tests.el (process-num-processors): New test.
* lisp/files.el (save-some-buffers-root): Put non-nil
symbol property 'save-some-buffers-function'.
(save-some-buffers): Check pred for the
symbol property 'save-some-buffers-function'.
(save-some-buffers-default-predicate): Mention
symbol property 'save-some-buffers-function'.
* lisp/subr.el (read-char-from-minibuffer-map):
Remap exit-minibuffer to read-char-from-minibuffer-insert-other.
(y-or-n-p-map): Remap 'exit' to y-or-n-p-insert-other.
(y-or-n-p): Don't mention RET in docstring. (Bug#51101)
Shorthands aren't symbols, they're text forms that 'read' into
symbols. As such, shorthands aren't candidates in these tables of
symbols. But in some situations, if no other candidates match the
pattern, we can e.g. complete "x-foo" to "xavier-foo" if the shorthand
(("x-" . "xavier-"))
is set up in the buffer of origin.
bug#50959
* lisp/help-fns.el (help--symbol-completion-table): Report
`symbol-help' category.
* lisp/minibuffer.el (completion-styles-alist): New 'shorthand'
style.
(completion-category-defaults): Link 'symbol-help' category with
'shorthand' style.
(minibuffer--original-buffer): New variable.
(completing-read-default): Setup minibuffer--original-buffer.
(completion-shorthand-try-completion)
(completion-shorthand-all-completions): New helpers.
