Accepting request 102198 from Archiving

drop pre-2005 compatibility patch which influences the output of bzip2. it is incredibly weird that one cannot reproduce the same bzip2 after bunzip2 on a non-opensuse system with the same bzip2 version. so, since the patch in question is only there to allow incredibly old bzip2 versions to decompress files created with a newer one it seems just about time to get rid of this patch. (forwarded request 101629 from apachelogger)
