Incosistent newline between operator and `do` keyword

```hs
a =
  ( b &~ do
      c
      d
  )
```
is ok, but
```hs
a =
  ( &~
      do
        c
        d
  )
```
is ugly and inconsistent with previous.

Context: I love to use endofunctions for optional arguments pattern, and State lenses in combination with (&~ do...) syntax are perfect means to write them. Extra line really bothers me.
