So, how would I know where one variable ends and the next one starts?

Given that this can be trivally written as shell loop, I don't see the
point.

Same here. E.g.:

pkg_info -e '*' | while read pkg; do
	case $(pkg_info -Q automatic "$pkg") in
	[yY][eE][sS])
	        echo "$pkg"
	esac
done

Same problem as the first, can be written as in the former example.
