Re: [PATCH 3/2] format-patch: use clear_commit_marks() instead of some adhocery

I think this makes sense, but the clear-commit-marks function
itself looks fishy.  I suspect a parent that has not been parsed
could be already marked in which case the current code would
leave it marked.  Don't we need this perhaps?
