     Alternatively, I wouldn't be upset if PSPP refuses to print any p-value

I think this is probably the best course of action at least in the short
term.
If not printing a p-value for this case is likely to confuse others, perhaps the
procedure should add a footnote indicating why the p-value is not output.

I had the same thought but I didn't know how easy it would be. Something like "Asymptotic approximations are inaccurate in samples of N<30."

The irony of this ... is that the Internet is
both almost-infinitely expandable, while at the
same time constrained within its own pre-defined
box. And if that makes no sense to you, just
reflect on the existence of Facebook. We have
the vastness of the internet and yet billions
of people decided to spend most of them time
within a horribly designed, fake-news emporium
of a website that sucks every possible piece of
personal information out of you so it can sell it
to others. And they see nothing wrong with that.
