Option to customize the -m message flag of cvs?

[Juanma Barranquero]

Hi.

For a long time I've been using CVSNT (http://march-hare.com/cvsnt/),
which is a free CVS derivative with better Windows compatibility,
though CVSNT is not Windows-specific at all (it works on GNU/Linux,
Windows, OS X, etc.).

The most recent release (2.5.04 (Zen) Build 3236) has been changed so
that commit messages added with -m get an additional text:

"
Committed on the Free edition of March Hare Software CVSNT Server.
Upgrade to CVS Suite for more features and support:
http://march-hare.com/cvsnt/";

There's been already a couple of such commits done against the Emacs
repository (by accident, of course).

The ad can be circumvented by using the new option -M instead of -m.
Unfortunately, "-m" is hardcoded in at least three places of
vc-cvs.el.

Would it be possible to add some kind of option to customize the
message flag passed to CVS?
