Actually it should be neither:
- font-lock-fontify-region will unnecessarily
  refontify the region if it was already fontified.
- jit-lock-fontify-now is wrong if the user is not using jit-lock.
- if the user decided not to use font-lock...

There's a need for a new function `font-lock-ensure-fontified' which would
do nothing if font-lock doesn't use any helper thingy like lazy-lock or
font-lock and which would call jit-lock-fontify-now (or the equivalent for
lazy-lock) otherwise.

ps-print currently uses ps-print-ensure-fontified to work around the lack of
font-lock-ensure-fontified.  And I'm pretty sure ps-print is not the only
such package.
