You can override the rsh command like the following (it can be
added to the ~/.emacs file):

(defadvice rsh (around prompt-for-username (host &optional user) activate)
  "If given a prefix argument, prompt for a user name."
  (interactive "sOpen rsh connection to host: \nP")
  (if (and user
           (interactive-p))
      (setq user
            (let ((minibuffer-setup-hook '(beginning-of-line)))
              (read-string "User name: "
                           (user-login-name) nil (user-login-name)))))
  (require 'shell)
  (let ((name (concat "rsh-" host )))
    (pop-to-buffer
     (if user
         (make-comint name remote-shell-program nil host "-l" user)
       (make-comint name remote-shell-program nil host)))
    (set-process-filter (get-process name) 'telnet-initial-filter)
    (telnet-mode)
    (setq telnet-count -16)))
