Well, whaddya know?! Forgot about it, I guess.

So all that's missing in this regard is an easy, non-Lisp way for users to do
the same thing - e.g. a button in Customize.

And then perhaps a good way for users to share their groups (a la skins). Maybe
just create an EmacsWiki page (e.g. GroupsAsSkins) where people can upload their
groups to share.

But that would mean also having Customize produce a `custom-add-to-group' entry
when you add a group to an option, so you could then extract that code from your
custom-file to share.
