Oh yes. What I meant is adding parent_repo_id to Repo model (sorry I was 
not very clear there). Like I said in reply to Todd's email, what 
happens when a parent repo of a feeded cloned repo is deleted? We need 
to either delete cloned repo or make it feedless. Also, feed does not 
always have parent repo id in it. We will have to go through all the 
repos and find one with this relative_url.

+1 to that. That was an option if we don't want to add parent_id to repo 
and still have a way to know that this is a cloned repo.
