Attached is an updated version of the patch with the following changes:
- Remove "backend+" prefix from server addresses returned by
  'nnoo-current-server'.
- Don't handle HTML in any special way when printing content.
- Fix group renaming when the last server of a backend inheriting from
  nnatom was of a different backend than the groups'.
- Fix newly parsed feed information being overwritten by old on-disk
  information (not sure how I missed this one before).
- Support all content types supported by Atom (I think).  Previously I
  stated Atom only supports plain text and (X)HTML.  This is wrong -
  Atom supports arbitrary MIME types too, and thankfully the encoding of
  binary data is defined to be base64, which is natively supported by Gnus.
- Change format of stored links - now an alist mapping MIME types (or
  lists of them) to a string to print is used.
- Support printing custom article-wide MIME headers.
- Probably some more minor stuff I don't remember.

Also attached is an updated version of the nnyt backend I use for
testing inheritance.
