Personally, I'd not limit this to loops.

	if (condition) {
        	if (another_condition)
                	action();
        }

You could argue the existing rule already covers these cases by
excluding selection and iteration statements from the "single statement"
in "Do not unnecessarily use braces where a single statement will do."
