Right; though the problem happens for regular strings too, they don't
necessarily have to be null terminated. And of course it would require
everybody editing the file to always remember to add terminating
nulls, which is much less user-friendly than what we have now.

That's a major PITA, certainly not justified for such a minor problem
that hasn't been demonstrated to cause any trouble in practice.
