Strange movement limits in *Ipconfig* buffer


From: Peter Brown
Subject: Strange movement limits in *Ipconfig* buffer

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list,
and to the gnu.emacs.bug news group.

In GNU Emacs 21.2.1 (i386-msvc-windows98.3000)
 of 2002-03-19 on buffy
configured using `configure --with-msvc (12.00)'
Important settings:
  value of $LC_ALL: nil
  value of $LC_COLLATE: nil
  value of $LC_CTYPE: nil
  value of $LC_MESSAGES: nil
  value of $LC_MONETARY: nil
  value of $LC_NUMERIC: nil
  value of $LC_TIME: nil
  value of $LANG: enu
  locale-coding-system: iso-latin-1
  default-enable-multibyte-characters: t

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Summary: 

M-x ipconfig brings up a buffer called *Ipconfig*.
Interactively (i.e., when I switch to that buffer), I can move about
it freely.  Programmatically, I am restricted to the top 29 characters
(or two lines).  The difference appears to be a bug (an annoying one
to me, since I want to get programmatic access to the data in the rest
of that buffer).

If I can be of further help in isolating and stomping this bug, please
let me know.

Details:

OS: Windows ME
Command line: C:\local\emacs-21.2\bin\runemacs.exe -q --no-site-file

I went straight to *scratch* and typed the following:

(defun phb-buffer-substr ()
  (set-buffer (ipconfig))
  (buffer-substring (point-min) (point-max)))

I evaluated that defun and then invoked the function, which returned:

"** Ipconfig ** ipconfig ** 
"

However, the actual contents of the *Ipconfig* buffer (with my
addresses edited out, since this isn't a network problem) are:

--begin buffer contents--
** Ipconfig ** ipconfig **
