Excuse me for the confusion. I talk her about another
issue, similar to what we have in bug #333138.

Now I tend to agree with Robert that this is a bug,
because fact of stdin being or not being tty should not
affect buffering/flushing of stdout/stderr. At least
this behaviour is rather strange and unexpected to
majority of *nix users, admins and programmers.

Thus I just recommend you add _explicit_ fflush(stderr)
there...
