There's fontification-functions, which is the hook around which jit-lock
is implemented.  

I'd recommend you use jit-lock instead (via jit-lock-register), tho,
because fontification-functions (despite its name) really only works
well with a single function (at least I don't know how to make it work
well with more than one, based on how it's currently defined).

Of course, if these are syntax-table properties, it will not solve all
problems, since the buffer-movement may still get buggy when it depends
on text that hasn't been displayed yet.

He probably wants it to work even when font-lock is disabled.
