Changelog for #799 [ci skip]
Improve on 0c56b9b3e5dc1b5457814db1de31032ca012f839.

- The options state really belongs with the hook when the instance is created.
  Better to pass it in the initializer than to have a separate `with` method
  for setting it.
- No need to wrap/unwrap the block with a proc an extra time; we can just
  pass the proc directly into the initializer.
Fix inner/outer subject confusion when using a named subject.

Fixes #800.

Note that the complexity of supporting `super` in a named subject makes me think that we should disable `super` in named subjects altogether instead.
Add missing changelog entry for #730.

Improve on e93b5d0abae49787837189fc248f30de392886ff.

- Ensure the NamedSubject override module gets inserted in the
  ancestor chain at the right place (this wasn't guaranteed before).
- Raise an error when `super` is used in a named subject. I don't
  think we should support it.
