Akim Demaille 39be113b1f all: show the rules in comments before the user actions ...

For instance, in the case of Bison's own parser:

    -  case 40:
    +  case 40:  /* grammar_declaration: "%code" "identifier" "{...}"  */
         {
           muscle_percent_code_grow ((yyvsp[-1].ID), (yylsp[-1]),
                                     translate_code_braceless ((yyvsp[0].BRACED_CODE), (yylsp[0])),
                                     (yylsp[0]));
           code_scanner_last_string_free ();
         }
         break;
