Synch with Gnus trunk:

2009-07-16  Katsumi Yamaoka  <yamaoka@jpl.org>
* nnrss.el (nnrss-request-article): Allow mml-to-mime to generate MIME
article without making inquiry to a user for unknown encoding.

* nnmaildir.el (nnmaildir--group-maxnum, nnmaildir--new-number)
(nnmaildir--scan): Assume i-node and device number that file-attributes
returns might be cons-cell.

2009-07-16  Teodor Zlatanov  <tzz@lifelogs.com>
* auth-source.el: Remove docs now in auth.texi.  Don't use
`gnus-message' for logging.  Add new variables `auth-source-debug' and
`auth-source-hide-passwords' and use them.

-;; Easy setup:
-;; (require 'auth-source)
-;; (customize-variable 'auth-sources) ;; optional
-
-;; now, whatever sources you've defined for password have to be available
-
-;; if you want encrypted sources, which is strongly recommended, do
-;; (require 'epa-file)
-;; (epa-file-enable)
-;; (setq epa-file-cache-passphrase-for-symmetric-encryption t) ; VERY important
-
-;; before you put some data in ~/.authinfo.gpg (the default place)
-
-;;; For url-auth authentication (HTTP/HTTPS), you need to use:
-
-;;; machine yourmachine.com:80 port http login testuser password testpass
-
-;;; This will match any realm and authentication method (basic or
-;;; digest).  If you want finer controls, explore the url-auth source
-;;; code and variables.
-
-;;; For tramp authentication, use:
-
-;;; machine yourmachine.com port scp login testuser password testpass
-
-;;; Note that the port denotes the Tramp connection method.  When you
-;;; don't use a port entry, you match any Tramp method.
