The text Matthias is quoting is from the POSIX specification
(http://pubs.opengroup.org/onlinepubs/009695399/utilities/jobs.html). I
think their point is moot though because Z-shell does not claim to be
POSIX compliant in its default mode. That said, when running Z-shell as
"sh", the output of `jobs -p` still includes the "extra" information:

    ~$ (exec -a sh zsh -c 'sleep 1 & sleep 2 & jobs -p')
    [1]  - 1022 running    sleep 1
    [2]  + 1023 running    sleep 2
