Indeed, as mentioned in the past a few times in various contexts,
I generally don't really want "git blame" (or its equivalent in other
VCS), instead I want "git log-and-diff FILE:NN-MM" which gives me the
history (hunks and accompanying log comments) of the lines between NN
and MM of FILE.

I use "git blame" to get each step of this history by hand, but it'd
be much better to get that history directly, which is probably cheaper
than a single "git blame".
