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).
