Oh, I didn't notice that. Indeed, the Emacs bzr repo is 2031 commits
lighter. In theory this difference seems like a disadvantage to git in
this test. In practice it's probably not because the length of history
does not seem to have much effect on git's performance. Anyway, the
main point was bzr, and git was there just to give some perspective
(for me personally too).
