Let's put it this way: we're not seeing a huge amount of load from git 
protocol requests, and I'm going to assume "git+http" protocol to be 
used only by sites behind braindamaged firewalls (everyone else would 
use git protocol), so I'm not really all that worried about it.

I'm not sure if "emulating a dumb server" is desirable at all; it seems 
like it would at least in part defeat the purpose of minimizing the 
transaction count and otherwise be as much of a "smart" server as the 
medium permits.
