bug#2459: 22.2.1: global-font-lock-mode does not turn off colors: ido.el, minibuffer prompt

[Jari Aalto <jari.aalto@cante.net>]

TEST

    emacs -Q -nw
    M-x ido-mode
    C-x C-f ~/   <notice the completions; in color>

    C-g
    M-x global-font-lock-mode <turn off>
    C-x C-f ~/   <notice the completions; *still* in color>

PROBLEMS

    After global-font-lock-mode is turned off:

    - ido-mode still displays completions in color.
    - Minibuffer prompt's text is still displayed in color.
