description:
Since "struct job" gained a pgrp member some time ago now, use it
instead of simply assuming that the pid of the first (leftmost) process
in a pipeline is the pgrp - someday we may switch things around and
create pipelines right to left instead, which has several advantages,
but which would invalidate the assumption which was being made here.
