This just copies the same local sample hgrc, except it sets the default path to the repo it was cloned from. This is cut-and-paste from the local sample hgrc, but I think it's acceptable, since the two pieces of code are right next to each other and they're small. There is danger of them going out of synch, but it would complicate the code too much to get rid of this C&P. I also add ui as an import to hg.py, but with demandimport, this should not be a noticeable performance hit.
