BF: made tests util digest.py friendly to python3
Merge remote-tracking branch 'origin/master'

* origin/master:
  RF: moving logwatch setup/sample logs under files/logwatch
  ENH: print rebans stats even if no "Failures" are logged, and reduce indentation in output
  ENH: untabified and reindented entire script for sane formatting (no functional changes)
  BF: logwatch -- fixing up regex for 'already banned'
  Sample logfiles to test logwatch services script
  Adjusting fail2ban logwatch script to match lines from 0.9 as well
We better check that installation doesn't cause any errors as well
