Not sure what you mean here. Should I move "err = errno;" outside the
innermost "if"?
>From my POV, if errno != EPIPE, we save it into err, and return that
(overridden by finish_command()'s return value, if non-zero). If errno ==
EPIPE, we're not interested in saving it, because we expect finish_command()
to return non-zero in any case.
