   however it does not work in GNU emacs 23, since it does not know
   the functions, vc-rcs-minor-part, vc-rcs-trunk-p
   I presume I have to try 24?

Those funcs are available as of Emacs 23.2, i believe.  In Emacs 23.1,
they were named ‘vc-minor-part’ and ‘vc-trunk-p’, respectively.  If you
cannot upgrade, you can obtain temporary relief with:

(defalias 'vc-rcs-minor-part 'vc-minor-part)
(defalias 'vc-rcs-trunk-p 'vc-trunk-p)

But it's probably better to get out alive while you can...
