cvsimport: use git-update-ref when updating

dscho · Junio C Hamano · commit 42277bc81ce2 · 2006-04-04T17:13:25.000-07:00
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 &lt;branch&gt; for update.
