Hm, that´s probably the reason why defadvice doesn´t appear in the
documentation.
So I guess should use advice-add instead --- and I can´t figure out how
to get that to work. I need to access the argument passed to the
function the advice is for, too. I tried to find examples, without
success.
What I have is:
(defadvice hi-lock-set-file-patterns (after lsl-hi-lock-set-file-patterns-advice activate)
(setq hi-lock-interactive-patterns (ad-get-arg 0)))
How would I do the same with add-advice (or whatever is appropriate)?

Yes, that´s exactly what I´m trying to avoid. There is no way to detect
when something changes in hi-lock.el in such a way that what I´m doing
doesn´t work anymore, or is there? Suddenly finding out that what I´m
trying to do doesn´t work anymore won´t be so great.
Taking a copy of hi-lock-mode and modify it isn´t a good solution,
either. There may be changes to the mode which my own version wouldn´t
have.
One change I´m thinking about is keeping the highlighting-patterns in a
separate buffer and applying them to several buffers. That way, you can
have several files that all use the same highlighting-patterns which
were generated on the fly, centralised for the whole project (or some
files of it). That´ll probably require quite a few modifications.
