I've committed this but I'm wondering if it would be sensible to add
STAT_DONE here? There's nothing to wait for if the job is done.
(This case is only for "wait" without an argument, so just wait for
everything we think is outstanding.)

By the way, unrelated to the bug (though it works around it), if you're
really interested in the status of the last background job, I think you
need to use "wait $!" anyway --- otherwise if the job is already
finished, "wait" will simply return immediately with status 0.  Waiting
for $! is the only special case available to handle the race.
