This avoids some race conditions (Bug#39683). E.g., if some other
program changes a file to a symlink between the time Emacs creates
the file and the time it changes the file’s permissions, using the
new flag prevents Emacs from inadvertently changing the
permissions of a victim in some completely unrelated directory.

* lisp/progmodes/cc-engine.el (c-forward-decl-or-cast-1): While attempting to
find a declaration's identifier, recast the latest found id. as that
identifier when there is no other type identifier and the result of the most
recent c-forward-type call is 'maybe or 'found. In the latter case, remove
the id. from the found types list, too.
* lisp/vc/vc-dir.el (vc-dir-ignore):
Pass relative file names to vc-ignore.
* lisp/vc/vc.el (vc-ignore): Move the responsibility of
constructing the ignore pattern (right now, most often a relative
file name) using a file name received from the user, here.
(vc-default-ignore): ...from here (bug#37189, see discussion).
Also clarify the docstring.
* src/data.c (wrong_type_argument): Restore check that the
object’s tag is valid, since invalid tags exist again.
* src/lisp.h (Lisp_Type_Unused0): New constant.
* doc/lispref/searching.texi (Char Classes): Warn about erroneous
usage of named character classes. Suggested by Stephen Leake
<stephen_leake@stephe-leake.org>.
* lisp/vc/vc-cvs.el (vc-cvs-ignore): Expand filename correctly
and pass on only the basename as the pattern.
(vc-cvs-append-to-ignore) Do not write duplicate strings to
.cvsignore. New optional parameter SORT to more explicitly
control sorting of the ignore entries. (Bug#37215)
* lisp/vc/pcvs.el (cvs-mode-ignore): Call 'vc-cvs-append-to-ignore'
with SORT argument.
* lisp/tempo.el (tempo-define-template): Update documentation string

all buffers at the same time.

(Bug#39555)
Most of the manual here addresses Message mode, yet talks about
'send-mail-function' which is used for Mail mode.
Fixing this completely requires more involved work, but for now at
least document the difference here.
* doc/emacs/sending.texi (Mail Sending): Mention
'message-send-mail-function'. (Bug#39639)
Most of the manual here addresses Message mode, and C-c C-c directly
above cites the Message mode command, not the Mail mode command.
* doc/emacs/sending.texi (Mail Sending): Fix reference. (Bug#39639)
When the eshell prompt is protected (e.g., with rear non-sticky,
inhibited movements, etc.), 'beginning-of-line' won't move to the
actual beginning of the line and therefore won't skip over the
prompt.
* lisp/eshell/em-prompt.el (eshell-previous-prompt): Use
'forward-line' to go to the beginning of the line, even if it's
protected. (Bug#39627)
* lisp/net/shr.el (shr-tag-code): Don't use the `default' font,
because it has properties that will override surrounding elements
(like <a...>) (bug#39504).
Incorrect escaping prevented these from working as intended.
Found by relint.
* lisp/progmodes/cc-defs.el (c-search-backward-char-property):
Add missing backslash.
* lisp/progmodes/simula.el (simula-mode):
Remove one backslash too many.
Problem reported by Ken Sasaki (Bug#39672).
* src/fileio.c (Ffile_directory_p):
Encode filename before giving it to file_directory_p.
This fixes a typo introduced in
