Ah, now I see what you've done.  Using header-line-format format is much
better than inserting a comment.  But using defadvice is much better
than redefining an 86-line function:

(defadvice shell-command (after insert-command-comment activate)
  "Insert COMMAND as a comment at the top of the output buffer."
  ;; Alternatives to truncating multi-line commands:
  ;; 1. Replace each newline with a semicolon.
  ;; 2. Truncate, but append an ellipsis.
  (save-excursion
    ;; (ad-get-arg 0) == COMMAND
    ;; (ad-get-arg 1) == OUTPUT-BUFFER
    (set-buffer (or (ad-get-arg 1)
                    "*Shell Command Output*"))
    (setq header-line-format
          (replace-regexp-in-string "%" "%%"
                                    (substring (ad-get-arg 0)
                                               0
                                               (string-match "\n"

(ad-get-arg 0)))
                                    nil t))))
