OK, good.

Does C++ mode in master support raw strings already? Is there a limit on 
how far you look for the end of the raw string, and if yes, how much is it?

This is unsubstantiated.

That's only an issue if `>' is on a different line than `<'. But yes, 
syntax-propertize-extend-region-functions exist for a reason.

If by "usual" you just mean the majority of cases you've encountered 
while using and developing CC Mode.

You've already expressed dislike for my solution. But sure, I will.

You still haven't asked a specific question. By now, I've given a 
thorough enough explanation of how things can go wrong that I have a 
hard time understanding what kind of example you want.

So, again: what question do you want answered? "Tell me something more" 
is just wasting my time.
