Subject: get_merge_bases: clean up even when there is no common commit.
X-Git-Tag: v1.4.2-rc1~77^2~6
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=2ef108013ec15e8d5feee6d5c42692ae956ee302;p=git.git

get_merge_bases: clean up even when there is no common commit.

Actually in this case we would have traversed a lot of commits, so cleaning
things up is even more important.
