Yes. My first impulse was along the lines of your initial fix, but then
I decided to try to figure out how we got a null stptr, since at first
glance, that shouldn't happen.

I think it's better to have the interpreter do what the program says,
which is

        fetch the translation for the string
        test it for nonzero/nonnull
        invert the result

and not try to be too smart otherwise.  If some idiot translator
explicitly supplies an empty translation for a nonempty original string,
gawk will still do what the program says it should do.

So, I think I want to leave well enough alone.
