Oh, I thought that was an XEmacs compat thing, since it's added by this
function:

---
(defun add-minor-mode (toggle name &optional keymap after toggle-fun)
  "Register a new minor mode.

This is an XEmacs-compatibility function.  Use `define-minor-mode' instead.

Does this doc string mean that one shouldn't use `add-minor-mode'
directly, but only through `define-minor-mode'?  But that everything
that `add-minor-mode' does isn't XEmacs compat stuff?

That does sound like a useful thing...  Since the major mode is
determined by the `major-mode' variable, what about a new
permanently-local variable `minor-modes'?  `define-minor-mode' would be
responsible for adding/removing itself to the variable.
