That reasoning makes perfect sense.

But this ls-files invocation that knows too much about how
list_untracked() computes things does not.

Why not

	my @add = list_untracked();
        if (@add) {
        	@add = list_and_choose({...}, @add);
	}
        if (!@add) {
		Nothing to do;
	} else {
		Run update-index
	}

or something instead?
