I could not find any changes regarding master file handling between
11.13 and 11.14.

Hey, I wanted to look for alternatives by testing this.  This was not
intended as a means for bashing the old implementation.

Well, I was able to delay the execution of the menu filters' guts with
stuff like (unless (eq major-mode 'fundamental-mode) ...) or by moving
the `easy-menu-add' calls to a position further down mode
initialization.

Actually I doubt it because I don't see a reason why it should not be
done.
