There were some bugs with registry pruning and precious entries, but
we fixed those quite a while ago. If you're running Emacs master, you
should have the Gnus that incorporates those fixes. On the other hand,
what you say above about the docstring makes me wonder, as in Gnus
master it doesn't say it would default to (marks). You're not loading an
external Gnus installation, are you?
