I use font-lock-syntactic-face-function, so I don't need to "see the whole
pattern" (I basically keep track of the intermediate state in the
parse-partial-sexp state). It works just fine (well, admittedly, I just
tried it and there's a bug in the code that in this case ends up placing
a string-fence char on the `s' instead of the `[').

That's why I used jit-lock-defer-multiline: I only refontify the whole thing
in the "deferred" refontification, not the on-the-fly one.
