[Sublime Text 3] Arrows break indentation

[voger]

I have this .exs file

defmodule Bob do
  import String
  def hey(input) do
    cond do
      "" == trim(input) -> 
        "Fine. Be that way!"
      ends_with?(input, "?") -> 
        "Sure."
      input == upcase(input) && input != downcase(input) -> 
        "Whoa, chill out!"
      true ->  
        "Whatever."
    end
  end
end

And in my keybindings I have

{"keys": ["ctrl+alt+/"], "command": "reindent", "args": {"single_line": false}},

But when I reident the file I get

defmodule Bob do
  import String
  def hey(input) do
    cond do
      "" == trim(input) ->
        "Fine. Be that way!"
        ends_with?(input, "?") ->
          "Sure."
          input == upcase(input) && input != downcase(input) ->
            "Whoa, chill out!"
            true ->
              "Whatever."
            end
          end
        end

This happens when the arrow -> is at the end of the line. If the statement is in the same line then the code formatting works fine.

defmodule Bob do
  import String
  def hey(input) do
    cond do
      "" == trim(input) -> "Fine. Be that way!"
      ends_with?(input, "?") -> "Sure."
      input == upcase(input) && input != downcase(input) -> "Whoa, chill out!"
      true ->  "Whatever."
    end
  end
end

And here is an example what happens with a longer file.

defmodule BinarySearch do
  @spec search(tuple, integer) :: {:ok, integer} | :not_found
  def search(numbers, key) do
    high = tuple_size(numbers) - 1
    _search(numbers, key, 0, high)
  end

  defp _search(numbers, key, low, high) do
    midpoint = low + div((high - low), 2)
    cond do
      low > high ->
        :not_found
        elem(numbers, midpoint) == key ->
          {:ok, midpoint}
          elem(numbers, midpoint) > key ->
            _search(numbers, key, low, midpoint - 1)
            elem(numbers, midpoint) < key ->
              _search(numbers, key, midpoint + 1, high)
            end
          end
        end

I did some minor change to Indent.tmPreferences which breaks indentation under conditionals and function definitions for the lines that end with arrow. But at least it is better than before. My regexp skills are very primitive and I haven't touched a sublime plugin before.
