gnus.texi: Remove mentions of `recent', which are now obsolete.

gnus-group.el (gnus-group-name-charset): Always return `utf-7' when decoding nnimap groups.
gnus.el (gnus-variable-list): Don't save `gnus-format-specs' in the newsrc file. It doesn't seem like an important optimisation any more.

gnus.el (gnus-article-mark-lists): Remove `recent'.
(gnus-interactive-exit): Extend to `quiet'.
gnus-sum.el (gnus-offer-save-summaries): Use it.
gnus-art.el (gnus-treat-hide-citation-maybe): Add more doc to the string.

gnus-spec.el (gnus-lrm-string-p): `bidi-string-mark-left-to-right' has been renamed.
(gnus-lrm-string-p): Include RLM and PDF, too.
gnus-int.el (gnus-open-server): Make the "denied" message clearer (bug#9225).
* plstore.el: Add documentation.
(plstore-mode): New mode to edit plstore file.
(plstore-mode-toggle-display, plstore-mode-original)
