Can R"( mean something else? 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.
