I suppose, but you either need to then know all of the other commands
which git-gc runs, and do them manually, skipping git-gc altogether,
or use git-gc, and end up rewriting the pack twice, ince using the
git-repack in git-gc, and then once manually so you can give the
options that you really want to give to git-repack.

Maybe the right approach is to have a way to specify default --window
and --depth as git configuration variables?  Looks like there is a
pack.window already, but not a pack.depth.

What if we add a pack.depth configuration option, and add only
--no-reuse-delta to git-gc?   Would that be better?
