Mark a rerun check with a short (run N) after its verdict, and word a re-hand-out neutrally

The forge clips a status to 140 characters, so the long sentence pushed the
verdict's own words out; and a paused holder's hand-back or a bus delay also
count as a delivery, so the cause is not claimed (novox/hq issue 594).
