Emacs indentation gives this:

Ref(1, Instance('twisted.internet.app.Application',
                persistenceVersion=7, services={}, udpPorts=[], gid=1000,
                connectors=[], uid=1000, tcpPorts=[(9080,
                                                    Instance('twisted.web.server.Site', sessions={},
                                                             resource=Instance('twisted.coil.web.ConfigRoot', children={},
                                                                               modules=[], widgets={'config':
                                                                                                    Instance('twisted.coil.web.AppConfiguratorPage', variables={},
                                                                                                             dispensers=Instance('twisted.coil.coil.DispenserStorage',
                                                                                                                                 dispensers={}})})))])

As you can see, it tries to align further arguments to a function
together with the opening parenthesis. I would assume that any other
auto-formatters use the same style, so you won't get any "sane"
indentation until you drop the nesting level (perhaps in favour of
method invocations).
