Emacs python-mode will actually align only one indent level in (instead of
aligning with the opening bracket) if you have a newline after the
bracket:

Ref(1, Instance(
    'twisted.internet.app.Application',
    persistenceVersion...

The tcpPorts bit should obviously be moved to another line, though.
