Yet another bug.  You do one shell command with lots of output and
*Shell Command Output* appears as a bottom window.  A second shell
command with a little output then causes the minibuffer to appear with
the same content as *Shell Command Output* most unprofessionally in a
double vision repeated display.

If you were schmart you would say "Oh, I've already got *Shell Command
Output* up there, no point in making a big deal about it in the
minibuffer."  Of course we are adding complexity, but whos schmart
idea was it to make such a peppy minibuffer in the first place?

As the shell-command doc string and the ChangeLog entries both say, it is
displayed in the echo area, not the minibuffer:

        * simple.el (shell-command-on-region): If output is 1 line,
        display it in echo area.

Anyway, here's an untested patch to get the behavior you want:

                   (message "%s"
                              (set-buffer buffer)

                   (kill-buffer buffer))
!                 ((and (= lines 1) (not (get-buffer-window buffer)))
                   (message "%s"
                              (set-buffer buffer)
