When PerlIO is initialized, the standard in/out/err are all explicitly
opened as textstreams. It seems that, lacking the crlf layer because
of :raw the newline translation is actually done natively; this is
rather surprising because it's kind of hard to trigger this edge case,
I'm not even sure why we'd want this to be possible in the first
place.
