@item gnus-confirm-mail-reply-to-news
@vindex gnus-confirm-mail-reply-to-news
-If non-@code{nil}, Gnus requests confirmation when replying to news.
+This can also be a function receiving the group name as the only
+parameter which should return non-@code{nil} if a confirmation is
+needed, or a regular expression matching group names, where
+confirmation is should be asked for.

If you find yourself never wanting to reply to mail, but occasionally
press R anyway, this variable might be for you.
+@item gnus-confirm-treat-mail-like-news
+@vindex gnus-confirm-treat-mail-like-news
+If non-@code{nil}, Gnus also requests confirmation according to
+@code{gnus-confirm-mail-reply-to-news} when replying to mail. This is
+useful for treating mailing lists like newsgroups.
