FYI, the idea behind this rule is said to be to able to use
a macro return(), f.e. for debugging you then can do:
#define	return(x) do {							\
	printf("returning from %s with %d\n", __func__, (x));		\
	return (x);							\
} while (0)

Given the this is a nifty feature and parentheses around the
return value don't hurt maintainability in any way IMO this
rule should stay.
