In 2009 I added tests demonstrating some of the erroneous behavior of
git-cvsimport.  The failing tests in t9601-t9603 are concrete examples
of the problems mentioned in the manpage.

If you haven't yet seen it, there is a writeup of the algorithm used by
cvs2git to infer the history of a CVS repository [1].  If your goal is
to make cvsps more robust, you might want to consider the ideas
described there.
