    feat: support trailing commas (>= Scala 2.12.2)
    
    Trailing commas were added in Scala
    [2.12.2](https://github.com/scala/scala/releases/tag/v2.12.2).
    
    Thought that before I jumped all the way in on the Scala 3 upgrade I would 
try
    patching something that has been bugging me w.r.t. the Scala 2 
implementation.
    
    Not 100% sure this is the most surgical fix. Will be testing locally and 
would
    love feedback.
