Right, but

	foo () {
	 trap 'false' DEBUG
	 true
	}

should not cause the exit status of foo to be nonzero.  Really the worse
case is

	foo() {
	 trap 'echo This command succeeds' DEBUG
	 false
	}

which should not cause foo() to return a zero status.  Installing a debug
trap shouldn't change the behavior of the debugged code unless it *also*
(intentionally) changes the command flow.
