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  <kahatlen@gmail.com>  (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  <julien@danjou.info>  (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.
