The way I read it, if using `append', rather than `prepend',
in the example above, EXAMPLE-L-WORD-FACE would change the
background iff FONT-LOCK-WARNING-FACE and
FONT-LOCK-KEYWORD-FACE, did not set the background colour.
Certainly in my Emacs setup, said faces have had their
backgrounds set explicitly.

Maybe a font-lock wizard can jump in with a better and/or
correct explanation.
