I assume here you're using 'plugin' as a variable; not requiring it to
be called plugin.  You probably want imp.get_suffixes() not a
hardcoded list.

I'm kind of surprised there isn't a standard module to do this...

I think this one is good; it's similar to the shell and some other
languages and adheres to the pattern that options can be moved around but
arguments/commands cannot.

I'd also like --no-plugins, which would disable them altogether, and
sometimes be a better choice than 'bzr builtin'.
