+;;; Commentary:
+
+;; See also: `erc-scenarios-base-channel-buffer-revival'.
+;;
+;; ERC 5.5 silently dropped support for the ancient option
+;; `erc-query-on-unjoined-chan-privmsg' because the tangled logic in
+;; and around the function `erc-auto-query' made it difficult to
+;; divine its purpose.
+;;
+;; Based on the name, it was thought this option likely involved
+;; controlling the creation of query buffers for unsolicited messages
+;; from users with whom you don't share a common channel. However,
+;; additional spelunking has recently revealed that it was instead
+;; meant to service a feature offered by most bouncers that sends
+;; PRIVMSGs directed at a channel you're no longer in and that you
+;; haven't received a(nother) JOIN message for. IOW, this is meant to
+;; support the following sequence of events:
+;;
+;; 1. /detach #chan
+;; 2. kill buffer #chan or reconnect in new Emacs session
+;; 3. /playbuffer #chan
+;;
+;; Note that the above slash commands are bouncer-specific aliases.
+;;
+;; Interested users can find more info by looking at this change set
+;; from the ancient CVS repo:
+;;
+;; Author: Mario Lang <mlang@delysid.org>
+;; AuthorDate: Mon Nov 26 18:33:19 2001 +0000
+;;
+;; * new function erc-BBDB-NICK to handle nickname annotation ...
+;; * Applied antifuchs/mhp patches, the latest on erc-help, unmodified
+;; * New variable: erc-reuse-buffers default to t.
+;; * Modified erc-generate-new-buffer-name to use it. it checks if
+;; server and port are the same, then one can assume that's the same
+;; channel/query target again.
