Yes, I know about it, even though it hasn't gotten much care and
attention.  But up until now it has only verified cvs2svn, not cvs2git
or cvs2hg...

I love your patches and have already applied them.  I would have applied
them even earlier but I was on vacation and out of internet contact
since last Thursday :-)

The patches all looked great and go in what I consider to be the right
direction.  I have to admit I did not review every last detail, but
since the script is in the contrib directory it doesn't (yet) need
extraordinary quality control.  That also means that I will be
especially accepting of additional patches to that script :-)

I see that you have made lots of other changes in your Mercurial repo
before and after the 5 that you referred to above.  Please let me know
specifically which other patches you would like me to consider for
cvs2svn trunk.

Please also consider visiting the #cvs2svn channel on irc.freenode.net
for real-time discussions.
