For info, this is the defadvice that exposes the `called-interactively' bug
(#3984):

(defadvice call-interactively (after icicle-save-to-history
                               disable activate)
  "Save command to `icicle-interactive-history'."
  ;; If command's input is not a parameterized (e.g. mouse)
  ;; event, record it.
  (let* ((fn   (ad-get-arg 0))
         (int  (interactive-form fn)))
    (when (and (symbolp fn)
               (consp int)
               (or (not (stringp (cadr int)))
                   (string= (cadr int) "")
                   (not (eq ?e (aref (cadr int) 0)))))
      (pushnew (symbol-name fn) icicle-interactive-history))))

This behavior is optional, so Icicles users can turn it off (it is off by
default) via option `icicle-populate-interactive-history-flag'.  And the doc
string of that option refers to Emacs bug #3948.  Still, it would be good to get
this Emacs bug fixed - especially, as Kai remarks, since the Emacs source code
now uses `called-interactively-p' all over the place.
