Oh, I missed that.  But then the only commands ever invoking git
gc --auto would be git rebase -i, git merge, git svn and git am.
I don't know if some people have repositories where they never use
any of those, but I certainly have repositories where I only ever
use git rebase -i and never any of the other.  'git commit' is
something everyone is bound to use and thus it would be the best
place for running 'git gc --auto'.

As for the performance impact, on my machine 'git gc --auto' runs
500 times per second in a loop on the git repository (it won't
call the hook unless repacking is necessary).  I suppose any
script calling git commit in a loop would do substantially more
work than git gc --auto itself.  And if that bit of performance
really matters, it could be invoked by git commit only if (rand()
% 20 == 0).

My two cents anyway.
