Merge changes made in Gnus trunk.

gnus.texi (Subscription Methods): Link to "Group Levels" to explain zombies.  (Checking New Groups): Ditto (bug#8974).
gnus.texi (Startup Files): Clarify that we're talking about numbered backups, and not actual vc (bug#8975).
gnus-group.el (gnus-read-ephemeral-bug-group): Bind the coding systems to binary before writing and reading the mbox files.
gnus.el (gnus-summary-line-format): Link to the info node for %U instead of trying to list them all (bug#8978).
pop3.el (pop3-open-server): Use :end-of-capability.
gnus-group.el (gnus-read-ephemeral-emacs-bug-group): Make sure that the id is always a number.
gnus-group.el (gnus-read-ephemeral-emacs-bug-group): Hook into debbugs mode, if possible.

-Gnus normally determines whether a group is new or not by comparing the

-@code{gnus-check-new-newsgroups} is @code{ask-server}, Gnus will ask the
-server for new groups since the last time.  This is both faster and

-groups altogether, so you may set @code{gnus-save-killed-list} to
-@code{nil}, which will save time both at startup, at exit, and all over.
-Saves disk space, too.  Why isn't this the default, then?

 Zombie and killed groups are similar to unsubscribed groups in that they
