Can we make log exclusive so that the inconsistency with diff
is removed?

It would break compatibility with old versions, and would mean
that we would have to decide what to do with "bzr log -rx"

I don't see why it has to be inclusive, and there have been
a few requests for some way to make it exclusive. "before:"
would allow you to make it inclusive much more easily than
it is to make the current one exclusive as well I believe.

Thanks,
