Formatter should fold long expression chain.

Long expression chain like this:  
```kotlin
import System.Console;

func max(a:int32, b:int32): int32 = if (a > b) a else if (a > b) a else if (a > b) a else if (a > b) a else if (a > b) a else if (a > b) a else if (a > b) a else if (a > b) a else if (a > b) a else b;

func main() {
    WriteLine(max(12, 34));
}
```
Should be wrapped by the formatter.
