.. almost :-) Here is a better version:
(defmacro history-push (newelt history &optional maxelt)
"Add NEWELT to the history list stored in the symbol HISTORY.
If symbol MAXELT is specified, the maximum length of the history is
specified by the value of that symbol. Otherwise, the maximum history
length is to the value of the `history-length' property on symbol
HISTORY, if set, or to the value of the `history-length' variable.
Remove duplicates of NEWELT unless `history-delete-duplicates' is nil."
(declare (debug (form sexp)))
(unless maxelt
(setq maxelt `(or (get ',history 'history-length)

`(let ((len ,maxelt))
(if history-delete-duplicates
(setq ,history (delete ,newelt ,history)))
(setq ,history (cons ,newelt ,history))
(when (integerp len)
(if (= 0 len)
(setq ,history nil)
(if (> (length ,history) len)
