I think this does what you are asking for:

(defun Return ()
"exit minibuffer and stop loop in read-string-list2"
  (interactive)
  (setq keepLooping nil)
  (exit-minibuffer)
)


(defun read-string-list2 (&optional prompt uniquify)
  "Construct a list of strings interactively from minibuffer.
  <ALT-RETURN> to terminate all items except the last, which is
  ended with <RETURN>."
  (interactive)
  (define-key minibuffer-local-map (kbd "<M-return>") 'exit-
minibuffer)
  (define-key minibuffer-local-map (kbd "<return>") 'Return)
  (let ((sl nil))
    (let (str)
      (setq keepLooping t)
      (while keepLooping
                   (setq str (read-string
                              (concat (or prompt
                                          "String")
                                      " (or RET to end list): ")))

        (if uniquify
            (add-to-list 'sl str t)
          (setq sl (append sl `(,str))))
        )
       (define-key minibuffer-local-map (kbd "<return>") 'exit-
minibuffer)
         )
    (message "%s" sl)
    sl))
