;; Short description on the problem...
;; Here are three functions from eev-rcirc.el.
;; They worked until 20210728, but from 20210905 onwards calling
;;
;;   (ee-rcirc-connected "irc.libera.chat")
;;
;; when I am connected to liberachat yields this error:
;;
;;   rcirc-buffer-process: Wrong type argument: bufferp, "*irc.libera.chat*"

(defun ee-rcirc-buffer (server &optional channel)
  "Return the name of an rcirc server buffer, or channel, or chat buffer."
  (if channel (format "%s@%s" channel server) (format "*%s*" server)))

(defun ee-rcirc-process (server)
  "If we are connected to SERVER then return its network connection process.
