I had a git repository for development of rsync and wanted to start
importing the upstream CVS with git-cvsimport, but git-cvsimport saw
that the git repository existed and insisted on updating a previous
import. This patch adds an -N option to git-cvsimport to force a new
import and updates the documentation appropriately.

I implemented this because I needed it; adopt it in the main git if you
like it.
