[nojaf]

Issue created from fantomas-online

Formatted code

match x with
| Foo f -> []
| Bar x ->
  "\n"
  + columnHeadersText
  + "\n"
  + seprator
  + "\n"
  + itemsText
|> Some

Reformatted code

match x with
| Foo f -> []
| Bar x ->
  "\n"
  + columnHeadersText
  + "\n"
  + seprator
  + "\n"
  + itemsText
  |> Some

Problem description

Fantomas was not able to produce the same code after reformatting the result.
The recent change to fix #1501 introduced this problem.
The body of the last clause needs to be further away from the infix that follows.

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.

_{Did you know that you can ignore files when formatting from fantomas-tool or the FAKE targets by using a .fantomasignore file?}

Can happen with 4 spaces indent as well:

match x with
| Foo f -> 
            "\n"
            + columnHeadersText
            + "\n"
            + seprator
            + "\n"
            + itemsText
| Bar x -> 
    // comment
    []
|||> Some
