This does not help: after deleting the .overview file from
News/agent/nntp/news.gmane.org/gmane/emacs/help (but retaining the
corresponding .agentview file), all marked (ticked) articles, as well as
all seen but unread articles, are missing from the summary buffer.
However, the good news is that bug has apparently been fixed in the mean
time: I updated from the trunk today and after opening gmane.emacs.help
with Gnus all the marks were intact, and remained so after closing and
reopening.  This is with the previous 14 MB .overview file reinstated.
(I was sent an email on March 19 from the testbed Emacs bugtracker
saying that Stefan Monnier had closed the bug, but it didn't give
details and I cannot tell from the change logs which change contains the
fix (I was away when the email was sent and wasn't able to update until
today).)
