Life is not black and white my friend, there are shades
of gray.  I feel bad for you if you read coding style rules
in a %100 literal sense with no room for interpretation.

People add extra parenthesis to add clarity, so you are
entirely misrepresenting these cases.

This was not a simple case of:

	return (A);

but more like something that looks as:

	return ((A & B) | (C ^ D));

and that is perfectly fine.
