I recommend you using **kwargs for all commands your plugin overrides.
And when you're run underlying bzr command just pass this **kwargs
to it run() method. Something like this:

class cmd_version(builtins.cmd_version):

     __doc__ = builtins.cmd_version.__doc__

     def run(self, **kwargs):
         return builtins.cmd_version.run(self, **kwargs)

In this case you don't need to update your plugin every time in trivial cases
like this one. I use such approach in my gzipped_bundle plugin, because
I override pull, merge and bundle commands and they often change signatures.
