Current behavior

defmodule ATest do
  describe "encode/2" do
    # DPT 24
    test "DPST 24-1" do
      assert {:ok,
              <<0x54, 0x68, 0x69, 0x73, 0x20, 0x66, 0x6F, 0x72, 0x6D, 0x61, 0x74, 0x20, 0x61,
                0x6C, 0x6C, 0x6F, 0x77, 0x73, 0x20, 0x74, 0x72, 0x61, 0x6E, 0x73, 0x6D, 0x69,
                0x73, 0x73, 0x69, 0x6F, 0x6E, 0x20, 0x6F, 0x66, 0x20, 0x76, 0x65, 0x72, 0x79,
                0x20, 0x6C, 0x6F, 0x6E, 0x67, 0x20, 0x73, 0x74, 0x72, 0x69, 0x6E, 0x67, 0x73,
                0x21,
                0x00>>} =
               Dpts.encode("24.001", "This format allows transmission of very long strings!")
    end
  end
end

See the 0x00 in a separate line.

Expected behavior

It should not have a separete line, just like it doesn't if there's less nesting.
