When creating a new message, message-send-mail uses an obsolete format
for the In-Reply-To header that includes additional information about
the originating message.  This patch changes the default to use the
rfc5322 approved format, but allow the obsolete format through a
defcustom.

* lisp/gnus/message.el (message-make-in-reply-to): Return only the
message-id of the originating message (the default) unless the new
custom variable message-header-use-obsolete-in-reply-to is non-nil.
* doc/misc/message.texi: Document the new custom variable
message-header-use-obsolete-in-reply-to.
* etc/NEWS: Update NEWS.

* doc/lispref/backups.texi (Reverting):
Add inhibit-auto-revert-buffers and inhibit-auto-revert.

* etc/NEWS: Add inhibit-auto-revert-buffers and inhibit-auto-revert.
Fix typos.

* lisp/autorevert.el (inhibit-auto-revert-buffers): New variable.
(inhibit-auto-revert): New macro.
(auto-revert-active-p, auto-revert-handler):
Check `inhibit-auto-revert-buffers'.

* lisp/dired.el (dired--inhibit-auto-revert): Remove.
(dired-buffer-stale-p): Don't set it.
(dired-map-over-marks, dired-internal-do-deletions):
Use `inhibit-auto-revert.

* test/lisp/autorevert-tests.el
(auto-revert-test08-auto-revert-inhibit-auto-revert)
(auto-revert-test08-auto-revert-inhibit-auto-revert-remote): New tests.

* doc/misc/org.org (External Links): Change HTTP example to use HTTP.
Changing it to HTTPS has been done before, but it's a mistake.  To avoid
making this mistake again, change the URL to orgmode.org to make it more
similar to the example on the next line, thereby contrasting the two.

* lisp/time-stamp.el (time-stamp-pattern, time-stamp-count): Document
how to update different time stamps on multiple lines.
* doc/emacs/files.texi (Time stamps): Add an example showing a time
stamp at the end of a file.
* etc/NEWS: Announce time-stamp format additions.
* test/lisp/time-stamp-tests.el: More title-case tests.

* doc/lispref/frames.texi (Multiple Terminals):
* lisp/frame.el (display-monitor-attributes-list): Better
documentation of what the 'source' key means on X.  (Bug#75936)

* doc/misc/tramp.texi (External methods): Precise remark on rsync speed.

* lisp/net/tramp-cache.el (tramp-connection-properties): Add link
to the Tramp manual in the docstring.
