[PATCH] Make find_commit_subject() more robust

Just like the pretty printing machinery, we should simply ignore empty lines at the beginning of the commit messages.

This discrepancy was noticed when an early version of the rebase--helper produced commit objects with more than one empty line between the header and the commit message.

	Aaaaand another patch from the rebase--helper front. I guess I'll
	call it a day with this one.
