    So let it rest until after the release.  Please!

Certainly this is for after the release, and we don't have to discuss
it now either.

The only question for now is what global-highlight-changes-mode
should do when turning the mode off.  Should we go to trouble
to maintain its peculiar behavior, or should we make it like
most global major modes.
