Well...  if the user wants the mode disabled in some mode, the user can
say (setq-local show-paren-mode nil) in the hook for the mode.  (And can
check whether it's enabled by just looking at that variable.)

On the other hand, it'd make the mode more regular -- perhaps the user
just wants to switch it on in just a particular buffer.

But we can't really change the names of the global(ized) version of the
mode, because that'd break people's setups.  So instead of having a
global-show-paren-mode/show-paren-mode, we'd have
show-paren-mode/show-parent-mode-this-buffer (or something), which is
also pretty confusing.

So taking all that into consideration, I think it'd better to just leave
things as they are, and I'm closing this bug report.
