I've just left some comments on this. It is almost there, but the way it 
checks if pushing a branch updates its upstream looks dodgy to me. The 
behavior wrt branches that are merged but are upstreams of other 
branches has changed so that the entire hierarchy is now preseved. I 
preferred it when we only kept the branch that was the upstream of the 
unmerged branch and deleted everything underneath but I'm happy enough 
if others prefer this new behavior.

Thanks
