Aha, I tried with two test functions, one with a key binding in its
doc (\\[universal-argument]) and the other without, and indeed, the
first one gets its advice info's font-locking removed and the other
doesn't.

I'll try to come with an easy fix, if at all possible, unless you beat
me to it (feel free to ;-)

Still, the other problem (docstrings missing) is much more serious.

Thanks,
