WIP white/black-list: Fix b-contains behavior

Up to this commit, --blacklist-contains would blacklist any entry that
matches any <text>.
This behavior has been changed to only blacklist any entry that contains
all <text> entries specified by multiple --blacklist-contains (or just 1
if there was only 1 flag).

TODO:
    - white/black-lists for test/extract for file format version 1 and
      2.
    - white/black-lists for create/test/extract for file format version
      0.
