Issue created from fantomas-online

Code

module M =
    let LongFunctionWithLotsOfParameters
        (aVeryLongParam: AVeryLongTypeThatYouNeedToUse)
        (aSecondVeryLongParam: AVeryLongTypeThatYouNeedToUse)
        (aThirdVeryLongParam: AVeryLongTypeThatYouNeedToUse)
        =
        // ... the body of the method follows
        ()

Result

module M =
    let LongFunctionWithLotsOfParameters (aVeryLongParam: AVeryLongTypeThatYouNeedToUse)
                                         (aSecondVeryLongParam: AVeryLongTypeThatYouNeedToUse)
                                         (aThirdVeryLongParam: AVeryLongTypeThatYouNeedToUse)
                                         =
        // ... the body of the method follows
        ()

Problem description

The Microsoft FSharp style guide had a recent change when it comes to long function definitions.
The original snippet is now what it should be.

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.

Should this PR include two more testcases? One where only 1 param is used and another one where a return type is used.
