At the beginning of the recursive name_rev() function it parses the commit it got as parameter, and returns early if the commit is older than a cutoff limit. Restructure this so the caller parses the commit and checks its date, and doesn't invoke name_rev() if the commit to be passed as parameter is older than the cutoff, i.e. both name_ref() before calling name_rev() and name_rev() itself as it iterates over the parent commits. This makes eliminating the recursion a bit easier to follow, and the condition moved to name_ref() will be moved back to name_rev() after the recursion is eliminated.
