I've made a few changes to "git blame" myself:
- fix breakage caused by recent revision walker reorganization;
- use built-in xdiff instead of spawning GNU diff;
- implement -S <ancestry-file> like annotate does.
Depending on the density of changes, it now appears that blame
is 10%-30% faster than annotate. I thought CVS emulator might
be interested to give it a whirl..
Sorry, forgot to mention... The updated blame will be in "next",
not in "master" yet.
