+
+       YYACCEPT, YYERROR, and YYABORT, as user actions, should not
+       destroy the RHS symbols of a rule.
+       * data/yacc.c (yylen): Initialize to 0.
+       Keep its value to the number of items to possibly shift.
+       In particular, a regular successful parse that ends on YYFINAL by
+       a (internal) YYACCEPT must not have yylen != 0.
+       (yyerrorlab, yyreturn): Pop the RHS.
+       Reorder a bit to emphasize the `shifting' bits of code.
+       (YYPOPSTACK): Now accept a number of items to pop.
+       * data/lalr1.cc: Likewise.
+       * data/glr.c: Formatting changes.
+       Use goto instead of fall through.
+       * doc/bison.texinfo (Destructor Decl): Complete.
