You mean at each commit, a list of changed lines is stored?
I and sussman is discussing another way on IRC right now. That's doing the
blame from the newest file and backwards. Then you could ask for ranges of
lines and stop early, get feedback earlier (think GUI editor) and stop
early if the whole file was changed sometimes (not sure if this owuld be
common, though).
