Nested cascades don't nest indentation

[munificent]

The formatter currently produces:

void main() {
  final object = outer(inner()
    ..innerProperty1 = 1
    ..innerProperty2 = 2)
    ..outerProperty = 3;
}

Note that innerProperty and outerProperty are at the same indentation depth even though there are cascades on different objects. I'd expect something like:

void main() {
  final object = outer(inner()
      ..innerProperty1 = 1
      ..innerProperty2 = 2)
    ..outerProperty = 3;
}

Is this related at all to #760

Probably.

Drive by: WIP tall style formatter outputs this, which I think is working as intended:

void main() {
  final object = outer(
    inner()
      ..innerProperty1 = 1
      ..innerProperty2 = 2,
  )..outerProperty = 3;
}

The forthcoming tall style handles argument lists and cascades differently. With the new style, you get:

void main() {
  final object = outer(
    inner()
      ..innerProperty1 = 1
      ..innerProperty2 = 2,
  )..outerProperty = 3;
}

That fixes the ambiguous nesting problem and looks pretty good to me.
