* When reloating files from a rpm, run the mv command directly,

not in a subshell; this is safer especially if odd filenames are
     involved.
   * When converting from rpm, only chmod each directory once, it was doing
     it many times for some directories before.
   * Fixed chmodding to use the correct path to the directory. This fixes
     file permissions in rpm's converted to other formats, a bug introduced
     at 7.0.
   * Fixed some undefined value warnings (which pointed out real but rare
     bugs).
   * Fixed a rare, but bad little bug. If you ran alien in a directory that
     had the suid/sgid bit set (as my home directory does), and generated
     debs and probably other formats, it generated packages with the root
     directory suid/sgid.
