Yes, really.  Depending on your usage pattern one will be more frequent
than the other.  Maybe in your usage pattern the second almost never
happens, but that's definitely not the case in general.

You can't know that "the user hasn't yet reached her
closing double quote".

On that we agree.

The error is on the first line of the string and it's indeed good to
highlight it (and font-lock.el should probably provide support for that).

What happens with the subsequent lines is a completely different question.

Yes, that's good (on the first line).
