buffer-offer-save and *scratch*

buffer-offer-save and *scratch*

[Kevin Rodgers]

In GNU Emacs 21.3.2 (i386-pc-solaris2.8, X toolkit)
  of 2003-05-22 on zeus
configured using `configure  --prefix=/opt/csw --with-xpm --with-jpeg 
--with-png --with-gif'
Important settings:
   value of $LC_ALL: C
   value of $LC_COLLATE: nil
   value of $LC_CTYPE: C
   value of $LC_MESSAGES: nil
   value of $LC_MONETARY: nil
   value of $LC_NUMERIC: nil
   value of $LC_TIME: nil
   value of $LANG: C
   locale-coding-system: nil
   default-enable-multibyte-characters: t

This form does not have its intended effect in my .emacs file
(i.e. buffer-offer-save still has its global default value of nil in the
*scratch* buffer):

(with-current-buffer (get-buffer "*scratch*")
   (setq buffer-offer-save t))

But if I immediately evaluate it in the *scratch* buffer, it works.

That is because at startup, Emacs sets the major mode of *scratch*
according to `initial-major-mode', _after_ your .emacs is read.
Changing major modes kills all local variables that are not
permanently local, including `buffer-offer-save'.

But `buffer-offer-save' should be permanently local.  Whether you want
to be offered to save the buffer or not has nothing to do with the
major mode.

Sincerely,

Luc.

So the fix is to put this in files.el, right after the defvar and
make-variable-buffer-local forms:

(put 'buffer-offer-save 'permanent-local t)

and the workaround is to put it in site-start.el -- right?  I can
confirm that workaround solves my problem.
