parse.y: brace after literal arg
* parse.y (symbol, dsym, parser_set_number_literal, parser_yylex): set state to END too not only ENDARG and after a literal, so that a left brace after it should be a primary block bound to the literal, which causes syntax error. [ruby-core:81037] [Bug #13547] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58641 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
