While reviewing the patch, I stared at that code for a good while
thinking that there was something about it I ought to remember but
couldn't, so thanks for the reminder (and j6t's too).

Considering that this patch is probably going in the wrong direction
and that if, when re-rolled, it takes a systematic approach testing
that the original code uses, then the "need" for test_stdout
effectively disappears, so this issue should go away too (but it's
good to remember, nevertheless).
