Thanks, Jens.

I assume that "sed"-ing out all parentheses would make the diff very
small and readable.

Do you think it would be a bad idea if I send a follow-on patch that
changes code like this:

	(cd dir &&
 	git update-index --add two &&
 	case "`git ls-files`" in
 	two) echo pass two ;;
 	*) echo bad two; exit 1 ;;
	esac
	) &&

to this:

	(
		cd dir &&
		git update-index --add two &&
		case "`git ls-files`" in
		two) echo pass two ;;
		*) echo bad two; exit 1 ;;
		esac
	)

It would have the benefit of touching all code in the subshell, so we
could see the effect on "exit" commands and whatnot.
