* lisp/registry.el (registry-collect-prune-candidates): This `cdr' was
  an error: it meant that the last key in the precious list, would be
  considered a nil. Since the precious list only contains the symbol
  'mark by default, marks were never considered precious.
* doc/misc/gnus.texi (Store arbitrary data): Fix typo: "marks" should
  be "mark".
