The function blame_entry_score is documented to approach
this exact problem that we are trying to solve here, so I agree
we should have a common heuristic.

While I do not think it is necessary to do such a refactoring within
the scope of this series, we should at least leave a NEEDSWORK
in-code comment next to the new heuristics code to remind those who
revisit the code of this possible small project idea, I would think.
