code: private void addNonExcactActions(Construction construction,
  	    ParserActionSet set, Map<Construction, ParserActionSet> actions) {
  	set.addActions(actions.get(new Terminal(construction.getName(), null)));
      }
docs: The method is needed for grammars where no keywords are available like
  Fortran.
  
  E.G.: If 'IF' is a keyword for the IF-construct and 'IF' also allowed to
  be a variable name, we need to add the actions for terminal
  NAME_LITERAL/'IF" and for NAME_LITERAL/*.
