Maybe, but I find it much more pleasant if the second line isn't highlighted.

We want the compiler and IDE to see the broken code, but we also want to do as much as we can to make the experience pleasant (and I find it unpleasant that inserting an unmatched '"' breaks syntax highlighting for the rest of the buffer.

As an example, Merlin does a great job at handling broken OCaml code.

Yes, I agree.  In the meantime, approximating that at the cost of a bit complexity in the Emacs mode seems good.
