Just to be clear: `cvs2svn' comes with a tool called `cvs2git'
(http://cvs2svn.tigris.org/cvs2git.html), is it what you used?  
That's what I used for Guile and didn't notice any problems.

The only thing "special" about `cvs2git' that I noticed is that CVS tags
are translated into Git commits that don't introduce any change, such as
http://git.savannah.gnu.org/gitweb/?p=guile.git;a=commit;h=63291d9c3ff2422155196f4263d5b0ea8c5fd973
 .
Are you seeing something different?

People on the `cvs2svn' mailing list were responsive and helpful, so you
might want to try there as well.

Thanks,
Ludo'.
