message:
  Merge changes made in Gnus trunk.
  
  Reimplement nnimap, and do tweaks to the rest of the code to support that.
  
  * gnus-int.el (gnus-finish-retrieve-group-infos)
  (gnus-retrieve-group-data-early): New functions.
  
  * gnus-range.el (gnus-range-nconcat): New function.
  
  * gnus-start.el (gnus-get-unread-articles): Support early retrieval of
  data.
  (gnus-read-active-for-groups): Support finishing the early retrieval of
  data.
  
  * gnus-sum.el (gnus-summary-move-article): Pass the move-to group name
  if the move is internal, so that nnimap can do fast internal moves.
  
  * gnus.el (gnus-article-special-mark-lists): Add uid/active tuples, for
  nnimap usage.
  
  * nnimap.el: Rewritten.
  
  * nnmail.el (nnmail-inhibit-default-split-group): New internal variable
  to allow the mail splitting to not return a default group.  This is
  useful for nnimap, which will leave unmatched mail in the inbox.
  
  * utf7.el (utf7-encode): Autoload.
  
  
  Implement shell connection.
  
  * nnimap.el (nnimap-open-shell-stream): New function.
  (nnimap-open-connection): Use it.
  
  
  Get the number of lines by using BODYSTRUCTURE.
  
  (nnimap-transform-headers): Get the number of lines in each message.
  (nnimap-retrieve-headers): Query for BODYSTRUCTURE so that we get the
  number of lines.
  
  
  Not all servers return UIDNEXT.  Work past this problem.
  
  
  Remove junk from end of file.
  
  
  Fix typo in "bogus" section.
  
  
  Make capabilties be case-insensitive.
  
  
  Require cl when compiling.
  
  
  Don't bug out if the LIST command doesn't have any parameters.
  
  2010-09-17  Knut Anders Hatlen  <address@hidden>  (tiny change)
  
            * nnimap.el (nnimap-get-groups): Don't bug out if the LIST command
            doesn't have any parameters.
  
  
  (mm-text-html-renderer): Document gnus-article-html.
  
  2010-09-17  Julien Danjou  <address@hidden>  (tiny fix)
  
            * mm-decode.el (mm-text-html-renderer): Document gnus-article-html.
  
  
  * dgnushack.el: Define netrc-credentials.
  
  
  If the user doesn't have a /etc/services, supply some sensible port defaults.
  
  
  Have `unseen-or-unread' select an unread unseen article first.
  
  
  (nntp-open-server): Return whether the open was successful or not.
  
  
  Throughout all files, replace (save-excursion (set-buffer ...)) with 
(with-current-buffer ... ).
  
  
  Save result so that it doesn't say "failed" all the time.
  
  
  Add ~/.authinfo to the default, since that's probably most useful for users.
  
  
  Don't use the "finish" method when we're reading from the agent.
  
  
  Add some more nnimap-relevant agent stuff to nnagent.el.
  
  
  * nnimap.el (nnimap-with-process-buffer): Removed.
  
  
  Revert one line that was changed by mistake in the last checkin.
  
  
  (nnimap-open-connection): Don't error out when we can't make a connection
  
  
  nnimap-related changes to avoid bugging out if we can't contact a server.
  * gnus-start.el (gnus-get-unread-articles): Don't try to scan groups
   from methods that are denied.
  * nnimap.el (nnimap-possibly-change-group): Return nil if we can't log
   in.
  (nnimap-finish-retrieve-group-infos): Make sure we're not waiting for
   nothing.
  * gnus-sum.el (gnus-select-newsgroup): Indent.

 ;;; Commentary:
 
-;; Todo, major things:
-;;
-;;   o Fix Gnus to view correct number of unread/total articles in group buffer
-;;   o Fix Gnus to handle leading '.' in group names (fixed?)
-;;   o Finish disconnected mode (moving articles between mailboxes unplugged)
-;;   o Sieve
-;;   o MIME (partial article fetches)
-;;   o Split to other backends, different split rules for different
-;;     servers/inboxes
-;;
-;; Todo, minor things:
-;;
-;;   o Don't require half of Gnus -- backends should be standalone
-;;   o Verify that we don't use IMAP4rev1 specific things (RFC2060 App B)
-;;   o Dont uid fetch 1,* in nnimap-retrive-groups (slow)
-;;   o Split up big fetches (1,* header especially) in smaller chunks
-;;   o What do I do with gnus-newsgroup-*?
-;;   o Tell Gnus about new groups (how can we tell?)
-;;   o Respooling (fix Gnus?) (unnecessary?)
-;;   o Add support for the following: (if applicable)
-;;       request-list-newsgroups, request-regenerate
-;;       list-active-group,
-;;       request-associate-buffer, request-restore-buffer,
-;;   o Do The Right Thing when UIDVALIDITY changes (what's the right thing?)
-;;   o Support RFC2221 (Login referrals)
-;;   o IMAP2BIS compatibility? (RFC2061)
-;;   o ACAP stuff (perhaps a different project, would be nice to ACAPify
-;;     .newsrc.eld)
-;;   o What about Gnus's article editing, can we support it?  NO!
-;;   o Use \Draft to support the draft group??
-;;   o Duplicate suppression
-;;   o Rewrite UID SEARCH UID X as UID FETCH X (UID) for those with slow 
servers

-Mail is read from mailbox(es) specified in `nnimap-split-inbox'.
-
-If you'd like, for instance, one mail group for mail from the
-\"gnus-imap\" mailing list, one group for junk mail and leave
-everything else in the incoming mailbox, you could do something like
-this:
-
-\(setq nnimap-split-rule '((\"INBOX.gnus-imap\"   \"From:.*gnus-imap\")
-                         (\"INBOX.junk\"        \"Subject:.*buy\")))
-
-As you can see, `nnimap-split-rule' is a list of lists, where the
-first element in each \"rule\" is the name of the IMAP mailbox (or the
-symbol `junk' if you want to remove the mail), and the second is a
-regexp that nnimap will try to match on the header to find a fit.
-
-The second element can also be a function.  In that case, it will be
-called narrowed to the headers with the first element of the rule as
-the argument.  It should return a non-nil value if it thinks that the
-mail belongs in that group.
-
-This variable can also have a function as its value, the function will
-be called with the headers narrowed and should return a group where it
-thinks the article should be splitted to.  See `nnimap-split-fancy'.
-
-To allow for different split rules on different virtual servers, and
-even different split rules in different inboxes on the same server,
-the syntax of this variable have been extended along the lines of:
-
-\(setq nnimap-split-rule
-      '((\"my1server\"    (\".*\"    ((\"ding\"    \"address@hidden")

-                                 (\"junk\"    my-junk-func)))))
-
-The virtual server name is in fact a regexp, so that the same rules
-may apply to several servers.  In the example, the servers
-\"my3server\" and \"my4server\" both use the same rules.  Similarly,
-the inbox string is also a regexp.  The actual splitting rules are as
-before, either a function, or a list with group/regexp or
