  | So the question is what exactly constitutes a foreground job whose status
  | has "not been reported."

I doubt it is stated anywhere, but I would treat any job whose status has
been collected in $? as having been reported.

So does bash in general, if one does

        ls; jobs

The jobs command doesn't report ls as being done, yet that status hasn't
been reported to the user any other way previously - $? was set however.

I don't see any reason there should be any difference for a process that
was run in one of the new non-forking command substitution type things, nor
when jobs is run from one of those.

 Does that exempt terminated foreground jobs whose
  | status would not be reported when the shell reaps jobs before printing
  | $PS1? That would be jobs that exited normally or jobs that exited due to
  | a signal we don't report on (SIGINT, possibly SIGPIPE, in interactive
  | shells). Or is it jobs that have changed status and the shell hasn't yet
  | determined whether it will notify the user about them?
