Guess renames and moves while converting a CVS repository

[npiguet at romandie.com]

I've tried doing a simple `git-cvsimport` followed by `hg clone` of the git
repository. While the sequence does produce a correct hg repo, it doesn't
seem to have guessed renames at all. Is there something special to configure
in hg-git to do the rename detection?
