Arrow functions in object literals

Currently, if an object literal contains an arrow function as one of its values, the next line is indented one level too much:

``` javascript
{
  one: () => 123,
    two: () => 'two',
      three: () => 'four'
}
```

It should be:

``` javascript
{
  one: () => 123,
  two: () => 'two',
  three: () => 'four'
}
```
