Talking of `vc-region-history' reminded me of a feature I find powerful,
would it be easily available: "showing blame information about original
authors of lines changed or removed in a given branch".

Maybe it'd be worth to think about that as well while implementing
`vc-region-history'. It seems to be its twin, no?
