T35: review round 2: a program's link inside a prompt keeps its target and carries the prompt's number in its id, and a prompt that starts inside a link left open opens it again with the number, so a prompt all in links still starts on its first row; controls vte runs inside an escape go on before it, so only the ESC waits and a long run of them keeps the pty reading
