Duplicate newline after shifting trivia between else if

[nojaf]

Issue created from fantomas-online

Formatted code

// check for match
if nargTs <> haveArgTs.Length then
    false (* method argument length mismatch *)
else if


    // If a known-number-of-arguments-including-object-argument has been given then check that
    (match knownArgCount with
     | ValueNone -> false
     | ValueSome n -> n <> (if methInfo.IsStatic then 0 else 1) + nargTs)
then
    false
else

    let res = typesEqual (resT :: argTs) (haveResT :: haveArgTs)
    res

Reformatted code

// check for match
if nargTs <> haveArgTs.Length then
    false (* method argument length mismatch *)
else if

    // If a known-number-of-arguments-including-object-argument has been given then check that
    (match knownArgCount with
     | ValueNone -> false
     | ValueSome n -> n <> (if methInfo.IsStatic then 0 else 1) + nargTs)
then
    false
else

    let res = typesEqual (resT :: argTs) (haveResT :: haveArgTs)
    res

Problem description

Interesting to see where the duplicate newline came from.
Definitely related to the changes of #2663.

Extra information

• The formatted result breaks my code.
• The formatted result gives compiler warnings.
• I or my company would be willing to help fix this.
