I've started using Tassilo's snippet in some of my projects and I like
it a lot, especially combined with org-mode's visibility cycling (cf
http://orgmode.org/faq.html#sec-1.2 ).
I've been running into the following issue: I turn on the
outline-minor-mode through a file-local variable, e.g. "-- -*-
mode:sql; mode:outline-minor -*- ". However, the headings are not
fontified until I manually toggle outline-minor-mode on and off. This
is somewhat strange, since the new entries do appear in
font-lock-keywords-alist. But even toggling font-lock-mode doesn't
make it work, only re-enabling outline-minor-mode. I'd love to hear
your thoughts on how to fix this :)
