commit d31e024cc98d37700879d4c8675fd10e678e44c1
Author: Phil Sainty <address@hidden>
Commit: Phil Sainty <address@hidden>

    Support FILE value t, meaning the minor MODE is already loaded
    
    If FILE is t then it is assumed that the mode is already loaded.
    (Note that you can also use 'emacs for this purpose).
    
    These FILE options are relevant to minor modes only.
