Error in 16.1

Hello,

In 16.1, it says:

> Use braces with all multi-line blocks.

But in the examples, there's a contradiction:

```
// good
if (test) return false;
```

And

```
// bad
function foo() { return false; }
```

The second one shouldn't say 'bad' since it's not multi-line block like the rule says.

Start at section 16.1 of the JavaScript Style Guide and compare the stated multi-line-block rule with the two examples in the issue. Correct the example or its label so the guidance is consistent, then verify that the section no longer contradicts itself.
