Subject: cvsimport: use git-update-ref when updating
X-Git-Tag: v1.3.0-rc3~22

cvsimport: use git-update-ref when updating

This simplifies code, and also fixes a subtle bug: when importing in a
shared repository, where another user last imported from CVS, cvsimport
used to complain that it could not open <branch> for update.
