Very cool, I love using this feature on github.

Looks like it looks for github repos, and will search up the tree and back down from there. However, this seems to mess up for me. If I go into a sub-directory in a repo and then try to open a file in the parent directory via `ctl+t`, then it tries to open that filename in the current directory, not from the parent (I'm using emacs as $EDITOR).

One other little thing, is there a way to get curses to cleanup better after itself? My terminal ends up with a relatively large blank spot after finding something, viewing it, and then closing emacs.
