Emacs got better at quoting shell arguments and the original value

and no context menu functions are called by e.g. describe-mode in wrong buffer
(bug#9923)

* lisp/mail/mail-utils.el (mail-rfc822-time-zone, mail-rfc822-date):
* lisp/timezone.el (timezone-make-arpa-date):
Simplify by using format-time-string with %z.

* lisp/mail/feedmail.el (feedmail-rfc822-time-zone):
* lisp/mail/mail-utils.el (mail-rfc822-time-zone):
Mark these should-have-been-internal functions obsolete.

Fix image load timekeeping bug

* lisp/image.el (image-animate-timeout): Fix bug that caused the
local variable time-to-load-image to be practically zero, instead
of the time it actually took to load the image.  I think
this bug was introduced in 2013-02-16T03:29:30Z!rgm@gnu.org.

Use time-convert in with-decoded-time-value

* lisp/calendar/time-date.el (with-decoded-time-value):
Prefer time-convert to current-time on the off chance that code
will use this obsolete macro even after current-time returns pairs.

Simplify message-make-expires

* lisp/gnus/message.el (message-make-expires):
Use time-add instead of doing it by hand.  This also calculates the
expiration time more accurately than the old code did.

Simplify message-unique-id etc.

* lisp/gnus/message.el (message-unique-id):
* lisp/net/sasl.el (sasl-unique-id-function):
Avoid unnecessary consing and reliance on internal timestamp
format by using (time-convert nil 'integer) which typically does
no consing, instead of using (current-time) and then ignoring
the subsecond parts of the generated list.

Prefer nil to (current-time) when either will do

* lisp/emacs-lisp/timer.el (timer-event-handler, run-at-time):
* lisp/gnus/gnus-score.el (gnus-score-date):
* lisp/gnus/gnus-search.el (gnus-search-query-parse-date)
(gnus-search-imap-handle-date):
* lisp/gnus/gnus-sum.el (gnus-user-date)
(gnus-summary-create-article):
* lisp/image-dired.el (image-dired-create-thumb-1):
* lisp/image/gravatar.el (gravatar-retrieve)
(gravatar--prune-cache):
* lisp/net/dbus.el (dbus-monitor-handler):
* lisp/net/tramp-gvfs.el (tramp-gvfs-handle-set-file-times):
* lisp/net/tramp-sh.el (tramp-sh-handle-set-file-times):
* lisp/net/tramp-sudoedit.el (tramp-sudoedit-handle-set-file-times):
* test/lisp/autorevert-tests.el (auto-revert--wait-for-revert)
(auto-revert-tests--write-file, auto-revert-test--wait-for):
* test/lisp/net/tramp-tests.el (tramp--test-print-duration):
Prefer nil to (current-time) when either will do, as this avoids
some consing.  Similarly, prefer omitting (current-time) arg
when this is equivalent.

Simplify cedet-utest-elapsed-time

* test/manual/cedet/cedet-utests.el (cedet-utest-elapsed-time):
Copy newer (circa-2011) implementation from elp.el, so that the
code matches its documentation again.

Use time-equal-p to compare timestamps in tests

* test/lisp/calendar/time-date-tests.el (test-days-to-time)
(test-time-since): Use time-equal-p to compare timestamps,
since the default form shouldn’t matter.

Add time-convert tests

* test/src/timefns-tests.el (time-convert-forms): New test.

Added dired-create-destination-dirs-on-trailing-dirsep

* lisp/dired-aux.el
(dired-create-destination-dirs-on-trailing-dirsep): New customization
option.
(dired-do-create-files): Use it.
(dired-create-destination-dirs): Mention the new option in the
docstring.

Merge from origin/emacs-28

e3427faf55 Fix typos and improve consistency in ERC manual
0bf10d5082 * test/Makefile.in (check-declare): Add missing --batch.
34f5656137 Document the subtleties of the 'cursor' text property

Make the Git stash commands available in vc-dir Git buffers

* lisp/vc/vc-dir.el (vc-dir): Call the backend-specific minor mode
if it exists.
* lisp/vc/vc-git.el (vc-dir-git-mode-map): New map.
(vc-dir-git-mode): New minor mode.
