Hi all,

Part two of my 'making checkouts work' series is making diff work.

Ironically, these two commands, which don't actually do anything, are
the ones that were most broken for checkouts.  I've done an audit of all
the places we use BzrDir.open_workingtree, and I can't see anything else
that looks dangerous.

Patch attached, or see bzr.ab
