Subject: Don't save digests in the playlist file.
X-Git-Url: http://git.tremily.us/?p=hooke.git;a=commitdiff_plain;h=66dda8a7b860f8a95cfe2e20c844a7519de8402d

Don't save digests in the playlist file.

They create dependency loops:
  digest_{i+1} = checksum(file with digest_i)
With the old way, exiting after
  $ hk.py -c 'new_playlist --output_playlist mylist'
          -c 'glob_curves_to_playlist ...*.curve'
          -c 'save_playlist --output mylist' -p
would complain of unsaved playlists.
