J26 item 2: the run-ask test expects a program's exit 7 to end its key failed

Since A-290 a run whose program exited other than 0 ends its key failed, the
reason saying the exit, its answer kept (steprun.finish); the test still
wanted passed. It now wants failed with "the program exited 7" and reads the
kept answer as before.
