I'd like to strongly object to this type of change.

The same goal can be accomplished by using a wrapper script for the cvs
command that changes -m to -M, or by changing the CVSNT sources not to
do this.

This patch is proposed because CVSNT chose to annoy they users into
paying for a license by inserting a commercial in the commit message.
And asking users to use the non-standard -M flag in order to avoid
that annoyance.

There is no guarantee that the same thing will not be done in the future
to other commands: like log, diff, annotate, etc.  Which would mean that
we'd have to continuously change both vc-cvs.el and PCL-CVS (which is
not done here, but it's as needed) to keep up.

The user needs to explicitly do something anyway, so better just have
the user either avoid CVSNT, change the CVSNT source (and recompile)or
use a wrapper script instead of littering the emacs code with this type
of needless changes.
