'suspend' shell function for BRL Bourne shell with job control

[Arnold Robbins]

Here is a quick shell function that will come in handy for those of you
who use the BRL Bourne shell with BSD job control.

suspend () {
	case "$-" in
	*J*)	set +J; kill -18 $$; set -J
		;;
	*)	kill -18 $$
		;;
	esac
}

Thanks to Doug Gwyn who suggested turning off job control with set +J.
