Can't edit file for which I have group write permission

[kf]

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.

In GNU Emacs 20.7.1 (i386-redhat-linux-gnu, X toolkit)
 of Mon Jul 30 2001 on stripples.devel.redhat.com
configured using `configure  --mandir=/usr/share/man --infodir=/usr/share/info 
--prefix=/usr --libexecdir=/usr/lib --sharedstatedir=/var --with-gcc --with-pop 
--with-x-toolkit i386-redhat-linux-gnu'

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

I tried to edit a file for which I have group write permission and emacs
wouldn't allow it, reporting that it was a read-only buffer.  As the same user
I was able to edit the same file (Makefile) using vi.

[ken@heidegger foomatic-20020212]$ ls -lda . Makefile
drwxrwxr-x    9 ken      test         4096 Feb 13 13:18 .
-rw-rw-r--    1 root     test         6297 Feb 13 13:17 Makefile
[ken@heidegger foomatic-20020212]$ id
uid=500(ken) gid=500(ken) groups=500(ken),501(test)

I don't remember having this same problem in any previous version of emacs.

If a nation values anything more than freedom, it will lose its freedom;
and the irony of it is that if it is comfort or money it values more, it
will lose that, too.
