sh: Do not prematurely discard stopped jobs in a wait builtin.

Browse Source 
If a job is specified to 'wait', wait for it to complete. Formerly, in
interactive mode, the job was deleted if it stopped.

If no jobs are specified in interactive mode, 'wait' still waits for all jobs
to complete or stop.

In non-interactive mode, WUNTRACED is not passed to wait3() so stopped jobs
are not detected.
