This isn't a sensible idea. because it wouldn't solve any of the
problems we have with the string-fence syntax.

Instead, maybe we should add a new syntactic symbol to Emacs, "one-line
string quote".  A string opened by such a delimiter would be terminated
either by the same quote again, or a newline.

This would have the advantage of making fontification easy, whilst still
allowing syntactic operations within an invalid string.  For example, in

    char *foo = "(
    )"

, the "s would have "one-line string quote" syntax and be fontified with
warning face, but a C-M-n from the ( would still move point to after the
), and all the electric-pair-mode stuff would still work.

This paragraph would still hold.
