Verbatim string with mismatched line endings triggers "failed syntax tree validation"

[belav]

Use "auto" line endings.
Format the following file

public class ClassName
{
    public string Value = @"EndThisLineWith\r\n
EndThisLineWith\n
";
}
CSharpier will trigger the "failed syntax tree vaildation" message because it is comparing the line endings in the verbatim string.
