    Confirm closing windows containing chat rooms.
    
    Getting the messages to feel right took quite a few iterations. Maybe we
    need one more case: when you only have one chat room in a window, and
    nothing else, the message from closing the window should probably be the
    same as it would have been if you'd hit ^W.
