* parse.y (parser_yylex): should clear parser->tokp as well.

  [ruby-dev:32250]

* parse.y: remove NEED_ASSOC that break test_parser_events.

* parse.y (parser_yylex): should not decrement line numbers at the
  end of file.

* file.c (rb_find_file_ext): search .rb files first through in the
  loadpath.
