No it has nothing to do with the language's syntax.

It's just a UI choice: Alan likes to highlight the opening string
delimiter of unterminated strings [ Not sure why CC-mode doesn't do the
same for unterminated comments, tho maybe it's just an oversight.  ]

I think this should not vary between major modes, IOW it should be
a separate feature that works on all major modes.
