Thanks for fixing the issues.

Indeed I see 3 of the tests failing. The issue is the existing
branches. I have the fix for them by changing the branch name. I will
push it and send another patch along with the above changes.

However, I am having problems in getting one test pass - "git branch
-C c1 c2 should add entries to .git/logs/HEAD". I'm trying to figure
it out.

"Branch copied" log is being added to .git/logs/HEAD. However, it
doesn't work in a similar way as -M option. Hence, it's not being
returned when we grep by ^0\{40\}.*$msg$.
