* lisp/progmodes/project.el (project--read-project-list): Simplify the
previous commit by utilizing the optional OMIT-NULLS argument to
'split-string'.
* lisp/progmodes/project.el (project-dired, project-eshell)
(project--read-project-list, project--write-project-list)
(project--add-to-project-list-front)
(project--remove-from-project-list): Adapt to the new 'project-root'.
* doc/emacs/maintaining.texi (Projects): Add a menu.
(Project File Commands): New subsection describing project file
commands (moved here from 'Working with Projects'). Describe the new
commands 'project-dired' and 'project-eshell'.
(Switching Projects): New subsection.
* etc/NEWS: Mention project.el changes.
* lisp/progmodes/project.el (project-switch-commands): Rename from
'project-switch-menu'.
(project--keymap-prompt, project-switch-project): Update after the
renaming.
* lisp/progmodes/project.el: Require seq.
(project--switch-alist): Remove in favor of the public
'project-switch-menu'.
(project-add-switch-command): Remove; not needed now that
'project-switch-menu' is a public alist.
(project-switch-menu): New variable mapping keys to project switching
menu entries.
(project--keymap-prompt, project-switch-project): Adjust to the new
'project-switch-menu' format.
* lisp/progmodes/project.el:
(project-find-regexp): Add to the list of 'switch' commands.
(project-switch-project): Use call-interactively so that the
former can read its arguments.
* lisp/progmodes/project.el:
(project--transient-p) Remove, not needed.
(project-current): Move project-find based on the directory here.
(project--remove-from-project-list): Only write if the list changed.
(project-find-project): Rename to project-prompt-project-dir.
Simply return the directory selected by the user.
(project-switch-project-find-file): Remove.
(project-switch-project-dired): Rename to project-dired and make
it follow the convention of existing projec tcommands.
(project-switch-project-eshell): Ditto.
(project-switch-project): Instead of passing the project instance
to the command, just bind default-directory.
* src/lisp.h (struct Lisp_Float): Declare via
GCALIGNED_UNION_MEMBER, not via GCALIGNED_STRUCT, since alloc.c
creates these in arrays and GCALIGNED_STRUCT does not necessarily
suffice to align struct Lisp_Float when it’s used in an array.
This avoids undefined behavior on oddball machines where
sizeof (struct Lisp_Float) is not a multiple of 8 and the compiler
does not support __attribute__ ((aligned 8)).
* src/alloc.c (union emacs_align_type): Move to here ...
* src/lisp.h: ... from here, and uncomment out some of the
types that alloc.c can see but lisp.h cannot.
* src/alloc.c (MALLOC_ALIGNMENT_BOUND): Remove.
(LISP_ALIGNMENT): Go back to yesterday’s version, except use
union emacs_align_type instead of max_align_t.
(MALLOC_IS_LISP_ALIGNED): Go back to yesterday’s version.
(maybe_lisp_pointer): Check against GCALIGNMENT, not LISP_ALIGNMENT.
* src/lisp.h (union emacs_align_type): Bring back.
This is simpler, and fixes a bug in the previous fix.
* src/alloc.c (MALLOC_ALIGNMENT_BOUND): Simplify by
using max_align_t, since the buggy implementations won’t
break this simpler implementation.
(LISP_ALIGNMENT): Simplify by just using GCALIGNMENT, since the
fancier implementation wasn’t correct anyway, and fixing it
isn’t worth the trouble on practical platforms.
* src/lisp.h (union emacs_align_type): Remove.
Problem reported by Eli Zaretskii (Bug#41321).
* src/alloc.c (MALLOC_ALIGNMENT_BOUND): New constant.
(LISP_ALIGNMENT): Lower it to avoid crashes on MinGW and similarly
buggy platforms where malloc returns pointers not aligned to
alignof (max_align_t). But keep it higher on platforms where this
is known to work, as it helps GC performance.
(MALLOC_IS_LISP_ALIGNED): Define in terms of the other two.
* src/alloc.c (stacktop_sentry):
* src/thread.c (run_thread):
Don’t overalign or oversize stack sentries; they need to be
aligned only for pointers and Lisp_Object, not for arbitrary
pseudovector contents.
* src/lisp.h (union emacs_align_type): New type, used for
LISP_ALIGNMENT.
The metamail package was last released in 1994, and has been removed
from most GNU/Linux distributions due to being buggy and unmaintained.
* lisp/mail/metamail.el: Move from here...
* lisp/obsolete/metamail.el: ...to here.
* etc/NEWS: Mention its obsoletion.
At least for me, 'auto-save-visited-mode' is very slow and blocks user
interaction for files visited over TRAMP. Therefore, I'd like a
mechanism to disable it for some buffers (namely, those visiting
remote files).
* (auto-save-visited-mode): Document that 'auto-save-visited-mode' can
be set to nil buffer-locally.
* etc/NEWS: Document new behavior.
Otherwise, we end up permanently modifying eshell-mode-map when
running eshell-command.
* lisp/eshell/eshell.el (eshell-command-mode): New mode, with map to
contain the bindings previously set by eshell-return-exits-minibuffer.
(eshell-return-exits-minibuffer): Make into obsolete alias for
eshell-command-mode.
(eshell-command): Use eshell-command-mode instead of
eshell-return-exits-minibuffer.
* lisp/progmodes/cc-langs.el (c-operators): Add co_await and co_yield to the
C++ value of "Exception" keywords.
(c-return-kwds): Create a C++ value containing co_return.
(c-simple-stmt-kwds): Add co_return to the C++ value.
Copyright-paperwork-exempt: yes.

This was missed in a previous commit to remove obsolete libraries.
Its deletion was already announced in NEWS.
* lisp/obsolete/levents.el: Delete file. This library has been
obsolete since 23.2.
