I keep one-line blocks unbraced when possible and my reasoning is definitely not to feel like a tough macho man. It's more like a mild form of OCD where any syntax that's not necessary just bothers me if I don't omit it.
Kidding aside, I can appreciate your feeling of OCD (I fight that urge too) but remember that most syntax is for humans, not machines. Using braces communicates intent to the reader; omitting them offers an opportunity to stumble.
The one line version isn't prone to goto fail, and to me reads very nicely.
if (x == 1) return;
if (x == 1)
return;
