ScalarStyle.Literal not rendering as I would expect?

[f2calv]

Firstly, great library, thanks 👍

I am persisting various objects to YAML files, some of which have string properties that are multi-line. My LiteralMultilineEventEmitter is working to a degree, however the format of the YAML multi-line indicator isn't what I was expecting/wanting.

Demo code;

using System.IO;
using YamlDotNet.Core;
using YamlDotNet.Serialization;
using YamlDotNet.Serialization.EventEmitters;
namespace TestApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            var obj = new
            {
                someString = "hello world",
                someMultiLineString = @"hello
world
123"
            };

            var serializer = new SerializerBuilder()
                .WithEventEmitter(e => new LiteralMultilineEventEmitter(e))
                .ConfigureDefaultValuesHandling(DefaultValuesHandling.OmitDefaults)
                .DisableAliases()
                .Build();
            var str = serializer.Serialize(obj);
            File.WriteAllText("c:/temp/test.yml", str);
        }
    }

    class LiteralMultilineEventEmitter : ChainedEventEmitter
    {
        public LiteralMultilineEventEmitter(IEventEmitter nextEmitter) : base(nextEmitter) { }

        public override void Emit(ScalarEventInfo eventInfo, IEmitter emitter)
        {
            if (eventInfo.Source.Type == typeof(string) && eventInfo.Source.Value is string value && value.Contains("\n"))
                eventInfo.Style = ScalarStyle.Literal;
            base.Emit(eventInfo, emitter);
        }
    }
}

The above code outputs;

someString: hello world
someMultiLineString: |-
  hello
  world
  123

However I was expecting;

someString: hello world
someMultiLineString: |
  hello
  world
  123

i.e. I would like to to have | (not |- with the extra hyphen), is there an override possible here or am I missing a configuration option?

There is not a way of omitting the chomp indicator (which is what the +/- after the | is). I'll add it as an enhancement later on down the road.
