Allow "git repack" users to specify repacking window/depth

Allow "git repack" users to specify repacking window/depth

[Linus Torvalds]

.. but don't even bother documenting it. I don't think any normal person 
is supposed to ever really care, but it simplifies testing when you want 
to use the "git repack" wrapper rather than forcing you to use the core 
programs (which already do support the window/depth arguments, of course).
