    Fix hang in outgoing INCR transfers.
    
    I'm not quite sure how this never got tested before, but I was missing
    a vital part of the protocol. When you do an incremental selection
    transfer, you repeatedly write the same X property on the destination
    window, and every time the receiving client deletes the property, you
    write the next value. But you can only _find out_ when the client has
    deleted it if you sign up for PropertyNotify events on the receiving
    window, and we weren't doing that.
