Steps to reproduce:

- Format the attached code
The result is:
--------------------------------------------------
class Foo {

    var seq: String[] on replace oldSlice[a..b] =  
        newSlice  
    


    
    


  {

        
        for (s in seq   
            [a
        
        
        
    

        
        
        
    
..b]){ println(s) } };
}


class A{
    public var seq:Number[] on replace  oldValue2[lo1..hi1] = newVals3{
        for(index in [hi1..lo1 step -1]){
            println(seq[index]);
        }

        println(oldValue2);
        println(newVals3);
    }
}
