} jobs here runs in a subshell, where there is no job control, so no
} information on jobs. It has always been this way. It's not particularly
} convenient, however. Maybe it's time someone thought about changing it.
What do you suggest, that we special-case the "jobs" command?
Zsh runs the left-hand-side of pipelines in a subshell and the right-
hand-side in a current shell so that stuff like
echo foo | read line
echo $line
will output "foo". Bash (I believe) runs the right-hand-side in a subshell
and the left in the current shell. I like zsh's way better.
