interactive指定子を作っちゃえば楽に置き換えられるんじゃね？
ってことで、こんな。

(in-package "editor")
(defun interactive-read-string-with-escape-sequence (prompt default history title)
  (list (decode-escape-sequence (read-string prompt :default default :history history) nil)))
(pushnew '(#\w . interactive-read-string-with-escape-sequence)
	 *interactive-specifier-alist* :test #'equal)
(defun interactive-read-regexp-with-escape-sequence (prompt default history title)
  (list (decode-escape-sequence (read-string prompt :default default :history history) t)))
(pushnew '(#\W . interactive-read-regexp-with-escape-sequence)
	 *interactive-specifier-alist* :test #'equal)

;; こんな感じで使う
;; 文字列
(defun search-forward-wes (pattern &optional noerror)
  (interactive "wSearch forward: "
    :default0 *last-search-string* :history0 'search)
  (search-command pattern nil nil (interactive-p) noerror))
;; 正規表現
(defun re-search-forward-wes (regexp &optional noerror)
  (interactive "WRe-search forward: "
    :default0 *last-search-regexp* :history0 'search)
  (search-command regexp nil t (interactive-p) noerror))
(export '(search-forward-wes re-search-forward-wes))
(in-package "user")
