globaloptions bug in optster

bug.py

#!/usr/bin/env python
"""
Demonstrates a bug in opster.

This is intended to have two subcommands, `edit` and `read`.
`read` takes a positional argument, `edit` takes none.

If you run the script as-is, like::

    python bug.py edit

or::

    python bug.py read somepage

you should see things working. However, if you switch the
line commented out at the bottom (which is intended to add
optional username/password parameters to each command),
neither of these will work - they quit out due to 'invalid
arguments'.

That is, adding two options globally makes previously valid
arguments invalid. I don't think this is the intended
behavior.
