JSON incompatible value serialization when Emitter has bestWidth

When using a JSON compatible value serializer with a Emitter (which has a small bestWidth) the resulting string is no longer JSON compatible because of emitted newlines.

var emitter = new Emitter(someWriter, 2, 5);
var jsonSerializer = new SerializerBuilder().JsonCompatible().BuildValueSerializer();
//...
jsonSerializer.SerializeValue(emitter, "This is a #single# line string", typeof(string));

The hash character causes a double quoted string to be emitted. But because of the bestWidth of 5 in the emitter the string is writton on multiple lines.

Sample output:

key: "This
  is a
  #single#
  line
  string"

As .NET fiddle was not working when writing this I attached a sample code to this message: JsonBug.cs.txt
