[PATCH] Add commands that git-gc runs underneath

From: Jari Aalto <jari.aalto@cante.net>

Message-ID: <lkbtwek0.fsf@cante.net>

git-gc is a higher level utility to "do the right thing". However there are many other lower level utilities for the house keeping and it is not clear what git-gc actually does. Adding the actual lower level command and their parameters explain "what's going on".x
