Subject: Create lightweight git tags (using the "reset" trick) for the incremental import... 
X-Git-Tag: v1.5.3-rc0~65^2^2~212
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=fc21f8a1dab090ceb63c479705104cbb95585a2f;p=git.git

Create lightweight git tags (using the "reset" trick) for the incremental import instead of full-blown ones. Also fix parsing the output of git name-rev for figuring out the last imported p4 change number.
