Add a condition for CodingStyle

Hi us,
When i see Documentation/CodingStyle, i find a missing case for "Chapter 3: Placing Braces and Spaces". We often know we should not use braces where a single statement. The first case is:
if (condition)
action();
Another case is:

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

     However, i can not find the second case. So i patch like following.

     Thanks.
     Best Regards.
     Harry Wei.

 This does not apply if one branch of a conditional statement is a single
 statement. Use braces in both branches.
