The Tailor support for bzr and the Bugs Everywhere support for bzr are
implemented by invoking bzr, not by using bzrlib.

I don't agree, because the purpose of the Command classes is to
interpret the user input.  The real work is (or should be) done
elsewhere.  In my view, trying to handle two different input styles in
the same code would reduce its readability, and make it likely that
changes to the user UI could affect the scripting UI, and vice-versa.
