jschoubben 69f76a53e7 Read a stop a later merge covered as covered, and keep it in deliveries while stalled lists it
A stop for a walk that never built its modules (issue 474) kept saying "error: stopped" on the forge and in
show after a later delivered merge carried its change to every machine. The stop stays final, as a covered
superseded member stays superseded (issue 442); its status, view, note and show now say covered and by which
merge, told once and from what is kept, so a restart or a stop covered before this tells it too. deliveries
dropped such a stop after a day while stalled still listed it; it now lists it as long as stalled does.
