I ran emacs -Q and so font-lock-mode came up enabled.  Good.  I then ran

  (global-font-lock-mode nil)

and it did turn off.  Looking at the documentation, I read the passage
below.  It makes me think that the argument of nil, since that's not
positive, would disable font-lock-mode, but it doesn't.  The function
really needs a negative argument.  The documentation should be fixed.

--8<---------------cut here---------------start------------->8---
global-font-lock-mode is an interactive compiled Lisp function in
`font-core.el'.

(global-font-lock-mode &optional ARG)

Toggle Font-Lock mode in all buffers.
With prefix ARG, enable Global-Font-Lock mode if ARG is positive;
otherwise, disable it.  If called from Lisp, enable the mode if
ARG is omitted or nil.

Font-Lock mode is enabled in all buffers where
`turn-on-font-lock-if-desired' would do it.
See `font-lock-mode' for more information on Font-Lock mode.

No need to apologize, mistakes do happen.  I'm glad we had this
figured out.

I'm closing this bug report, then.

Thanks.
