    builtin.1: Bring in some enhancements from FreeBSD.
    
    It is modeled after what they did but based on what we actually have in
    our shells' source.
    
    * Use "No**" to mark commands which exist externally but are implemented
      as a script executing the builtin.
    
    * Some further explanations and mdoc fixes.
