Looking at show-paren-mode again -- I thought we'd agreed to make it a
globalized minor mode instead of a global minor mode?  I.e., define it
with `define-globalized-minor-mode'.  Did that prove to be difficult to
do (i.e., not backwards-compatible)?

If we do that, then we'd define it exactly like global-font-lock-mode is
defined (with the turn-on-paren-mode-if-desired logic).

I don't see why the default value of a new `paren-mode-global-modes'
variable would affect people who are saying (show-paren-mode 1) in their
init files?  It should only affect those who haven't made any such
customisation already.
