I'd love to hear from other reviewers, but I am inclined not to merge this request. I am not fond of the bracket-less syntax -- rather than put it on one line, I would prefer to see the more verbose but far clearer bracketed syntax:

if (foo) {
    bar();
}

@nickmooney, I prefer the same way as you: to put brackets even for one line syntax. When you have more lines after if and no brackets then it could be like a trap (possibility of a bug because of lack of the brackets) and you need a little more time to process and find out what code will be executed in if statement.

I have the feeling that @gherlein followed the pattern: there were no brackets in the code before, so he didn't introduced them in his fix. I can understand this point of view.
