        * BUGFIX: format_default() in autodie::exception no longer
          returns a string with file and line attached.  This would
          cause the file and line information to appear twice when
          format handlers would choose to fall back to the defaults.
          The file and line information is now always added by
          stringify().  (RT #47520, thanks to Michael Schwern)

        * BUGFIX: Exceptions thrown by 2-argument open() are more likely
          to specify the mode as 'for reading' when no explicit
          mode was given.  (RT #47520, thanks to Michael Schwern)
