What about doing a diff of the blames? It should do the same thing (except
the +/- would be at the begining of the lines). Well, not exactly, because if
there was a change, that was reverted again, blames would change, so it would
appear here, but that's probably rare enough to ignore (if you don't even
want to see it rather than not).
