While I mostly agree, CodingStyle says:

------------------------------------------------------

Do not unnecessarily use braces where a single statement will do.

	if (condition)
		action();

and

	if (condition)
		do_this();
	else
		do_that();

------------------------------------------------------

Perhaps that should be "with single line statements" instead.
