cvs2svn version 2.0 (Aug 2007) totally changed how cvs2svn deduces
changesets.  Any results from before that are utterly irrelevant to
modern times.

The changes between version 2.0 and version 2.4 (Sep 2012) have done a
lot more to improve the quality of the conversion.  The state of the art
is far beyond what it was four years ago.

I look forward to your results (whether positive or negative).

Yes, we have a rather extensive test suite that includes lots of CVS
perversions.  See run-tests.py and the CVS repositories under test-data.
 Unfortunately, the tests mostly cover only 2svn conversions, but since
most of the tricky work is in the common code that infers the CVS
history, cvs2git benefits from the tests too.

This discussion is getting pretty cvs2svn-specific, so we should
probably move it over to the cvs2svn-dev mailing list.
