- Remove docs/CHANGES; see git release tag description.
- Remove docs/CREDITS; see git history.
- Deprecate filters. Filters used to be necessary for getting
https or Atom feeds. Since both of these were very common, everybody
had to use filters. Now snownews reads https and Atom natively
and filters just aren't needed any more for most people. So keep
supporting them, but stop mentioning them favorably in the docs.
- Remove the bugzilla example script. Having contributed scripts in the
main repository is a bad idea because I can't test them and thus
have no idea whether they work. They were never even installed by
default, making discoverability a problem.
