Fix indentation inconsistencies

[GHGibonus]

resolves #128 . The proposed fix removes some code that I tried to manually test. The code was probably intended to do what my pull request does (but didn't work).

I manually tested the following cases:

• Indentation on union types:

  type Bool
      = False
      | True

• The pipping operator:

  f x =
      tail x
          |> drop 5
          |> reverse

• The PR do not change the indentation behavior for certain operators:

  cathello x =
      x
      ++ "hello"
      ++ " world"

• Various if else expressions:

  if x > 10 then
      True
  else if x < 5 then
      False
  else
      True

  if x > 10
  then True
  else False

  if x > 10
  then True else False

  No situations seemed problematic, apart from nested if else with various levels of indentations. The same behavior showed in master.
