[PATCH] git-cvsimport-script: handling of tags
This patch changes git-cvsimport-script so that it creates tag objects instead of refs to commits, and adds an option, -u, to convert underscores in branch and tag names to dots (since CVS doesn't allow dots in branches and tags.) Signed-off-by: Junio C Hamano <junkio@cox.net>

The 'HEAD' branch from CVS is imported to the 'origin' branch within
the git repository, as 'HEAD' already has a special meaning for git.
