Re: can't turn off font-lock

[Richard Stallman]

    That's not fontification, those are faces set by other features.  If
    you place the cursor on one of the characters you think are fontified,
    and type "C-u C-x =", Emacs will show you the face's name: you will
    see that those are not font-lock faces.

When modes set up faces manually, they are supposed to set a
`font-lock-face' property rather than `face'.  That way, Font Lock
mode controls whether those faces actually appear on the screen.

If one of these modes fails to do that, we should change it.
