  21 # Description:
  22 # Verify redaction works as expected with respect to deleted files
  23 #
  24 # Strategy:
  25 # 1. A file on the delete queue counts as deleted when using it to calculate
  26 #    redaction.
  27 # 2. A file that is removed in the tosnap of an incremental, where the fromsnap
  28 #    is a redaction bookmark that contains references to that file, does not
  29 #    result in records for that file.
