Yeah, we usually try not to be overly flexible for that reason, but
given that "git shell" is so limited that rewriting its services
wholesale is not all that much of a deal, I think it is OK.

I however wonder if it is worth admins' time and effort to add
features to "git-shell" using this new facility, or if they are
better off using something more established like gitolite once they
want to go fancier beyond what the basic "git-shell" offers.
