Comment (by karsten):

 arma suspectes that `bzip2 -9` might already have reduced tarball size a
 lot.  Tested with two tarballs:

 || '''tarball''' || '''bzip2 -1''' || '''bzip2 -9''' || '''xz -9''' ||
 || consensuses-2014-04 || 241M || 217M || 21M ||
 || votes-2014-04 || 4.8G || 4.4G || 172M ||

 So, it seems that switching from `bzip2 -1` to `bzip2 -9` would not have
 made that much of a change compared to `xz -9`.
