Merge from gnus--rel--5.10 Patches applied: * gnus--rel--5.10 (patch 112-114) - Update from CVS 2005-09-07 Reiner Steib <Reiner.Steib@gmx.de> * lisp/gnus/spam-report.el (spam-report-gmane): Make it work without X-Report-Spam header. Gmane now only provides Archived-At. This is only used if `spam-report-gmane-use-article-number' is nil. (spam-report-gmane-spam-header): Removed. Not used anymore. * lisp/gnus/nnweb.el (nnweb-google-wash-article): Print a message if article is not available. 2005-09-07 TSUCHIYA Masatoshi <tsuchiya@namazu.org> * lisp/gnus/gnus-art.el (gnus-mime-display-single): Decode text/* parts content before displaying. 2005-09-06 Reiner Steib <Reiner.Steib@gmx.de> * lisp/gnus/mml-smime.el: Remove defvar of gnus-extract-address-components. 2005-09-06 Katsumi Yamaoka <yamaoka@jpl.org> * lisp/gnus/mm-view.el (mm-display-inline-fontify): Disable support modes.
