* Kay Roepke found a nasty bug when debugging AST-constructing
   composite recognizers.  If the input state was null to the  
constructor,
   super class constructor created a new parser state object.
   Later, though we passed the argument state not this.state
   to the delegate constructors, forcing them to share a different
   state objects!  Changed state to this.state in Dbg.stg constructors.
