| re: eval and &. Well, input for eval is rescanned noninteractively,

| prompts while it chugs through an eval.

I suppose.  But it surprised me while using ``--'', just now.

Actually async notification is not really what I had in mind.  I was
thinking that when rc does happen to wait(), it could collect all the
statuses and put them in $astatus.  The the prompt function could print
them if you wanted them.
