It gives the following:

  // column  limit             V
  int a = condition1 ? result1
        : conditio2 ? result2
        : loooooooooocondition
            ? result2
        : dition3 ? resul3
                  : resul4;
  
  // column  limit             V
  int a = condition1
            ? loooooresult1
        : conditio2 ? result2
                    : result4;

i.e. the long result is wrapped and gets an extra indentation.
I have tried quite a bit to "fall back" to the old behavior when there is this kind of wrapping, but this always created other situations which got brocken because of this: so finally I choose to stay consistent, and apply the same behavior whenever there are chained conditionals.

This ones is indeed aligned like this.
