> I'm not sure it's completely documented anywhere. Two parts; 1) I prefer braces over any multi line block, irrespective if its a single statement or not. This is, afaik, not strictly documented in coding style. Rationale is that missing braces are bad, and the larger the single statement, the harder it is to be sure it is in fact a single statement. 2) If one leg needs braces, then both should get it. This is in fact part of CodingStyle.
