global-auto-revert mode doesn't revert fully

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

In GNU Emacs 21.2.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

1. Turn on global-auto-revert-mode.
2. Open a CVS-controlled file in Emacs.
3. Do a CVS update outside of Emacs that brings out a newer version of
   the file.
4. Emacs will revert the contents of the buffer, but not the version
   number (as displayed in the mode line).  If you do any VC
   operations from within Emacs against that file, the VC commands
   will use the original version of the file as if it was current.

Thank you.  This will be fixed in the next non-bug-fix-only release.
I.e. probably 21.4.

I agree that that's an annoying bug. Here's a fix.

Add this to your .emacs:

(defun vc-reload-version-info ()
  "Re-read a file's version information after an external edit.

Meant to be added as to `after-revert-hook'."
  (when (vc-backend buffer-file-name)
    (vc-file-setprop buffer-file-name 'vc-workfile-version
                     (vc-call workfile-version buffer-file-name))
    (vc-mode-line buffer-file-name)
    (force-mode-line-update)
    )
  t)

(add-hook 'after-revert-hook 'vc-reload-version-info)
