Limits on programmatic movement in *Ipconfig* buffer?

Limits on programmatic movement in *Ipconfig* buffer?

[Peter Brown]

M-x ipconfig brings up an *Ipconfig8 buffer with lots of useful info
in it.  I find that when I switch to the buffer interactively, I can
move about the whole buffer, but programmatically I seem to be limited
to the first line or two.  Why can't I move about the buffer
programmatically?  Is this just something I don't know, or a bug?

Thanks for help/pointers.

Peace,

Details:

OS is Windows ME.

runemacs -q --no-site-file.

(emacs-version)
"GNU Emacs 21.2.1 (i386-msvc-windows98.3000)
 of 2002-03-19 on buffy"

Yank/type into *scratch* and eval:

(defun phb-buffer-substr ()
  (set-buffer (ipconfig))
  (setq phb-str (buffer-substring (point-min) (point-max)))
  (length phb-str))
    => phb-buffer-substr

(phb-buffer-substr)
    => 28

phb-str
    => "** Ipconfig ** ipconfig ** 
"

The actual contents of the *Ipconfig* buffer are as follows (with
addresses edited out):

** Ipconfig ** ipconfig **
