Re: How global is a define-global-minor-mode mode?

[Richard Stallman]

    Now back to the tests. If the above was a bit hard to grasp then maybe 
    the test will help. To run the tests first load this file and customize 
    the defcustom, define-minor-mode and define-global-minor-mode, all to t. 
    Then restart Emacs and load the file again and now look in the *Message* 
    buffer for the result.

That seems to be what define-minor-mode produces now, when the minor
mode is global.

This cannot be done for a minor mode that is normally local
because customizing a variable is always global.
