I agree the help message and the tutorial should be fixed.

As a separate issue, I think we should change the behaviour to be what
bradb expected, i.e. "bzr diff -r 40" is equivalent to 39..40. The
behaviour of diffing 40 to the current version is less commonly used,
and should be easy to get with "40..".
