If you folks don't think that this is a generally useful change to
define-global-minor-mode, I think I could do what I need if there was
an optional turn-off function.  Suppose instead of adding :only-new
EXPR the macro was changed to allow an optional :turn-off FUNC
keyword.  Would this be deemed more acceptable?  If this function were
supplied then instead of arbitrarily turning off the mode in all
exsiting buffers, it would call the function to possibly do so.
