I'm not sure I like the prompting when there's lots of files, where
lots > 1. Perhaps you can just print out "Diffing n files ..." then at
least the user knows why it's taking a while. And better still make it
interruptable so I can ctrl-c it.

Also it'd be nice to do something prettier when the tool isn't found:

$ bzr diff -r -2.. --using mgdiff
There are 2 files with differences to review
Do you wish to continue [Y/n]?
bzr: ERROR: exceptions.OSError: [Errno 2] No such file or directory
  at /usr/lib/python2.4/subprocess.py line 975
  in _execute_child
