Log message:
	Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
	error recovery loops.  This patch is based on
	<http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
	Also, augment the similarity between lalr1.cc and yacc.c.
	Note: the locations of error recovery rules are not correct yet.
	* data/lalr1.cc: Comment changes to augment the similarity between
	lalr1.cc and yacc.c.
	(YYERROR): Goto to yyerrorlab, not yyerrlab1.
	(yyerrlab1): Remove, but where it used to be (now the bottom part of
	yyerrlab), when hitting EOF, pop the whole stack here instead of
	merely falling thru the default error handling mechanism.
	(yyerrorlab): New label, with the old contents of YYERROR,
	plus the following change: pop the stack of rhs corresponding
	to the production that invoked YYERROR.  That is how Yacc
	behaves (required by POSIX).
	* tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
	fail.
