I.e. how to customize font-locking into "fruit salad".

No.  The fast and painful way would be to learn a bit about regular
expressions and write them in lisp.    If the script that did it was
reg-ex based, it ought to be reasonably simple.  See the SAS reg ex's
in the code which are a good example, or the extended C++ or Java
fontlocking, which is much closer to what you are thinking about.

I don't know if anyone else has time to do this (my time is limited as
I can't work on this during my work anymore).
