These are the number of objects "git push" (actually, git-send-pack, I
think) needs to look at more closely, AFAIUI. It's a pretty arbitrary
number. You see it sometimes during pull, too.

89 is the number of objects which need to be transmitted. Of those,
80 were compressed by diffing them to some other object (which might,
in turn, be a diff).
