Hi Alan,

the whole thing needs to be reflected from bottom. Not tied to 
exceptions like font-lock-dont-widen.

Why syntax-ppss might be useful at all? You told me the case lately: it 
provides a cache.

Okay. But when we really need the cache?

The solutions IMHO is first to restrict all usage of syntax-ppss to real 
necessity,  employ parse-partial-sexp as far as possible instead. Once 
syntax-ppss is reduced and restricted, fixing and tailoring it should be 
easier.

Cheers,

Andreas
