Store as attributes on object. If 'args' is None or not supplied, uses 'sys.argv[1:]'. If 'object' is None or not supplied, creates a new OptionDummy object, stores option values there, and returns a tuple (args, object). If 'object' is supplied, it is modified in place and 'getopt()' just returns 'args'; in both cases, the returned 'args' is a modified copy of the passed-in 'args' list, which is left untouched.
