Andrew G Cohen ecfc13e416 Introduce nnselect backend for gnus ... This new backend allows gnus to handle arbitrary sets of messages spanning multiple groups, even when these groups are from different backends and different servers. All gnus glue is removed from nnir (leaving only the backend search functions) and gnus search-related processing is done through nnselect. In appropriate places 'nnir' has been replaced by 'nnselect' or 'search'. * etc/NEWS: Document the change. * doc/misc/gnus.texi: New documentation for nnselect and update searching and thread-referral sections. * lisp/gnus/nnselect.el: New file. * lisp/gnus/nnir.el: Remove all gnus glue, leaving only searching capability. Improve documentation strings. * lisp/gnus/gnus-group.el (gnus-group-read-ephemeral-search-group, gnus-group-make-search-group): New functions. * lisp/gnus/gnus-msg.el (gnus-setup-message, gnus-group-news, gnus-summary-news-other-window): Update to work for nnselect. Fix gnus-newsgroup-name wrangling. *lisp/gnus/gnus-registry.el (gnus-registry-action,gnus-registry-ignore-group-p): Make work from nnselect. * lisp/gnus/nnheader.el (nnheader-parse-head, nnheader-parse-nov): Rework and consolidate header parsing. * lisp/gnus/gnus-agent.el (gnus-agent-regenerate-group): * lisp/gnus/gnus-cache.el (gnus-possibly-enter-article): * lisp/gnus/gnus-cloud.el (gnus-cloud-available-chunks): * lisp/gnus/gnus-msg.el (gnus-inews-yank-articles): * lisp/gnus/gnus-sum.
