I don't claim that my suggested implementation is final; perhaps a way to
override certain existing messages could be included.  (One could already
simply let-bind the variable `optional-message' to pretend that "Quit" was
the last one, but that would fail when the existing message was some other
optional message to be overwritten.  As a kludge, one could call
`optional-message' with and without the let-binding, but at that point the
existing implementation is probably better.)
