Synch with Gnus trunk

Synch with Gnus trunk
=====================
2010-03-23  Katsumi Yamaoka  <yamaoka@jpl.org>

 * gnus-art.el (canlock-verify): Autoload it for Emacs 21.

 * message.el (ecomplete-setup): Autoload it for Emacs <23.

 * mml-sec.el (mml-secure-cache-passphrase): Default to t that is
 password-cache's default if it is not bound.
 (mml-secure-passphrase-cache-expiry): Default to 16 that is
 password-cache-expiry's default if it is not bound.

 * pop3.el (pop3-list): Don't use 3rd arg of `split-string' which is not
 available in Emacs 21.

 * auth-source.el (auth-sources): Fix up definition so extra parameters
 are always inline.

2010-03-22  Martin Stjernholm  <mast@lysator.liu.se>

 * nnimap.el (nnimap-verify-uidvalidity): Fixed bug where uidvalidity
 wasn't updated after mismatch.  Clear cached mailbox info correctly
 when uidvalidity changes.
 (nnimap-group-prefixed-name): New function to avoid some code
 duplication.
 (nnimap-verify-uidvalidity, nnimap-group-overview-filename)
 (nnimap-request-group): Use it.
 (nnimap-retrieve-groups, nnimap-verify-uidvalidity)
 (nnimap-update-unseen): Significantly improved speed of Gnus startup
 with many imap folders.  This is done by caching the group status from
 the imap server persistently in a group parameter `imap-status'. (This
 was cached before too if `nnimap-retrieve-groups-asynchronous' was set,
 but not persistently, so every Gnus startup was still very slow.)

 * auth-source.el: Set up autoloads.  Bump to 23.2 because of the
 secrets.el dependency.
 (auth-sources): Add optional user name.  Add secrets.el configuration
 choice (unused right now).

2010-03-20  Teodor Zlatanov  <tzz@lifelogs.com>

 * gnus-sum.el (gnus-summary-make-menu-bar): Let
 `gnus-registry-install-shortcuts' fill in the functions.

 * gnus-registry.el (gnus-summary-misc-menu): Declare to avoid
 warnings.
 (gnus-registry-misc-menus): Variable to hold registry mark menus.
 (gnus-registry-install-shortcuts): Populate and use it in a
 `gnus-summary-menu-hook' lambda, under "Gnus"->"Registry Marks".

 * nnimap.el (nnimap-decode-group-name, nnimap-encode-group-name):
 In-place substitutions for the group name encoding/decoding.
 (nnimap-find-minmax-uid, nnimap-possibly-change-group)
 (nnimap-retrieve-headers-progress, nnimap-possibly-change-group)
 (nnimap-retrieve-headers-progress, nnimap-request-article-part)
 (nnimap-update-unseen, nnimap-request-list)
 (nnimap-retrieve-groups, nnimap-request-update-info-internal)
 (nnimap-request-set-mark, nnimap-split-to-groups)
 (nnimap-split-articles, nnimap-request-newgroups)
 (nnimap-request-create-group, nnimap-request-accept-article)
 (nnimap-request-delete-group, nnimap-request-rename-group)
 (nnimap-acl-get, nnimap-acl-edit): Use them.  Replace `mbx' with
 `encoded-mbx' for consistency.
 (nnimap-close-group): Call `imap-current-mailbox' instead of using the
 variable `imap-current-mailbox'.

 * gnus-agent.el (gnus-agent-fetch-articles, gnus-agent-fetch-headers)
 (gnus-agent-regenerate-group): Use `gnus-agent-decoded-group-name'.

2010-03-20  Bojan Petrovic  <bpetrovi@f.bg.ac.rs>

 * pop3.el (pop3-display-message-size-flag): Display message size byte
 counts during POP3 download.
 (pop3-movemail): Use it.
 (pop3-list): Implement listing of available messages.

2010-03-20  Mark Triggs  <mst@dishevelled.net>  (tiny change)

 * nnir.el (nnir-get-article-nov-override-function): New function to
 override the normal NOV retrieval.
 (nnir-retrieve-headers): Use it.
