Deserializing string with newlines adds extra lines

[superyyrrzz]

Reproduce code:

            var obj = new
            {
                Data = @"first line
second line
    third line with indentation
"
            };

            var serializer = new Serializer();
            string yaml = serializer.Serialize(obj);
            var deserializer = new DeserializerBuilder().Build();
            var deserialized = deserializer.Deserialize<Dictionary<string, string>>(yaml);

            Console.WriteLine(deserialized["Data"]);

Expect result:

first line
second line
    third line with indentation

Actual result:

first line
second line

    third line with indentation

The intermediate yaml is:

Data: >+
  first line

  second line

      third line with indentation

It seems the default serializer chooses folded scalar style, but it will introduce extra empty line when some line contains indentation. I can workaround this by using ScalarStyle.Literal as mentioned in #246 (comment), but I this it's a bug as data is changed after serialization and deseriazation. The serializer may not use folder style as default scalar style.

I find this issue only happens when using \r\n line endings. \n works well.

Hi!
I've the same issue. I am making my own DSL. It is dynamically resolve yaml files, so I have to use Dictionary<object, object> and can't use attributes to avoid this issue. Is there any progress in fixing this bug?
