Correct. I tried to explain why regular font-locking doesn't "just
work" and you need a more conservative approach. But it's not easy to
come up with an approach that is conservative enough not to have
highlighting leaking due to unterminated strings and similar problems,
and radical enough to font-lock normal strings. It's hard and a lot of
work which is why I'm looking for prior art in this area. Almost
anyone who has written a comint-mode must have considered the same
problem I'm describing.
