Allow line break after return to avoid excessive indenting/aligning

Issue created from fantomas-online

Code

let f () =
  async {
    let x = 2
    return some rather long |> stuff that |> uses piping |> to' demonstrate |> the issue
  }

Result

let f () =
    async {
        let x = 2

        return some rather long
               |> stuff that
               |> uses piping
               |> to' demonstrate
               |> the issue
    }

Better (IMHO)

let f () =
    async {
        let x = 2

        return
          some rather long
          |> stuff that
          |> uses piping
          |> to' demonstrate
          |> the issue
    }

Problem description

I find that excessive right-aligning damages the readability (see #657 for reasoning; other related issues are #658, #659).

IMHO it would be best if Fantomas avoided excessive right-aligning by default, but I'd be happy just to have the ability to configure this.

Extra information

• The formatted result breaks by code.
• The formatted result gives compiler warnings.
• I or my company would be willing to help fix this. (I'll help in any way I can except implementation; I don't have the capacity to ramp up on a new codebase now)

Thanks for reporting @cmeeren, maybe we can do the same thing here as we do with multi line yield!.
