Merge changes made in Gnus trunk.

message.texi (Insertion Variables): Document message-cite-style.
nnimap.el (nnimap-open-connection-1): Allow `network-only', too.
gssapi.el: New file separated out from imap.el to provide a general Kerberos 5 connection facility for Emacs.
message.el (message-elide-ellipsis): Document the format spec ellipsis.
message.el (message-elide-region): Allow the ellipsis to say how many lines were removed.
gnus-win.el (gnus-configure-frame): Protect against trying to restore window configurations containing buffers that are now dead.
nnimap.el (nnimap-parse-flags): Remove all MODSEQ entries before parsing to avoid integer overflows.
 (nnimap-parse-flags): Simplify the last change.
 (nnimap-parse-flags): Store HIGHESTMODSEQ as a string, since it may be too large for 32-bit Emacsen.
gnus-art.el (gnus-article-treat-body-boundary): Fix boundary width on XEmacs, which was one character too wide.
gnus-sum.el (gnus-articles-to-read): Use gnus-large-newsgroup as default number of articles to display.

gnus-int.el (gnus-open-server): Ditto.

 @section Insertion Variables
 
 @table @code
+@item message-cite-style
+@vindex message-cite-style
+The overall style to be used when replying to messages. This controls
+things like where the reply should be put relative to the original,
+how the citation is formatted, where the signature goes, etc.
+
+Value is either @code{nil} (no variable overrides) or a let-style list
+of pairs @code{(VARIABLE VALUE)} to override default values.
+
+See @code{gnus-posting-styles} to set this variable for specific
+groups. Presets to impersonate popular mail agents are available in the
+@code{message-cite-style-*} variables.
+
+@item message-cite-reply-position
+@vindex message-cite-reply-position
+Where the reply should be positioned. Available styles are
+@code{traditional} to reply inline, @code{above} for top-posting, and
+@code{below} for bottom-posting
+
 @item message-ignored-cited-headers
 @vindex message-ignored-cited-headers
 All headers that match this regexp will be removed from yanked
