Thanks!
This works - sort of. First of all, not all faces are set correctly
until I edit something in the respective line. And M-x
font-lock-fontify-buffer doesn't help - I don't understand this,
actually. (Tested on emacs -Q.)
Even worse, if I add ("foo" . italic) to the list above, occurrences of
"foo" don't get italicized. (M-x describe-face italic shows that my
computer /can/ display this face properly.)
What am I doing wrong?
