Several issues:

* Ghost <nowiki></nowiki> tag pairs appearing

* Syntax being normalized

 1)
  ! foo !! bar !! baz
  becomes
  ! foo
  ! bar
  ! baz

  Both are the same but should roundtrip if possible.

 2)
  Row separators
  {|
  |-
  ! foo
  |-
  | bar
  |-
  |}
  becomes:

  {|
  ! foo
  |-
  | bar
  |}

  Although the first and last separator (|-) are optional, they should roundtrip
  if possible.

 3) Syntax being broken due to new line insertion
  ! foo !! bar !! baz
  becomes:
  ! foo
  !! bar
  !! baz

  This is not just syntax appearance, this is actually broken. Because of the new lines, the output of 3) is actually difference, because it will display the second exclamation mark of each heading.
