Subject: [PATCH 0/1] commit-graph: avoid unnecessary tag deference when merging

Hi,

Here's a patch that Peff and I were kicking around from a couple of
months ago when we were investigating deploying commit-graphs at GitHub.
Particularly, we were looking into why merging two commit-graphs after a
write with '--split' took as much time as we were seeing in our
infrastructure.

This patch avoids an unnecessary tag dereference in
'merge_commit_graph()', which can improve the running time of a
commit-graph write by around ~7.4% on average.

Thanks in advance for your review.
