Reprinting file without changes line break changes

Parsing and reprinting

``` js
// I have a parent
newNode.parent
&& (
(// Or I did but its different than the one I have now.
!originalNode.parent ||
newNode.parent.key !== originalNode.parent.key
)
)
```

outputs

``` js
// I have a parent
newNode.parent
&& (
(// Or I did but its different than the one I have now.
(!originalNode.parent || newNode.parent.key !== originalNode.parent.key)
)
)
```
