If that's all you want to do, then "(if pop-up-frames" is (trivially)
the only answer.

But I'm pretty sure that's not the answer you're looking for because I'm
pretty sure that "test if pop-up-frames is non-nil" was *not* the
intention behind the code.  Now, it might be true that the coder doesn't
know his own intention.  It's a common problem.
