That reminds me of https://bugs.debian.org/868738, which I tracked down
to perl's "die" helper using errno to determine the exit status instead
of deterministically using 128. I wasn't able to track it down further
t/t0021/rot13-filter.pl doesn't have any similar suspect constructs, but
thought I should mention it anyway.
