Autorevert mode bug

From: Deepak Goel
Subject: Autorevert mode bug
Date: Fri, 12 Jan 2001 00:53:36 -0500 (EST)

In GNU Emacs 20.3.1 (sparc-sun-solaris2.6, X toolkit)
 of Tue Oct 20 1998 on attitude.csc.umd.edu
configured using `configure  --prefix=/usr/local/gnu'

I use emacs -q -no-site-file. 

then, i open file "hi" in view-mode, and then i turn on autorevert

Then, in another window, i modify "hi" via: cat aa > hi.

emacs does correctly revert "hi".  the only problem is that it turns
off the view-mode.  I think it should leave the new "h" in the view-mode.. 

what if i want to just view a buffer and autorevert it as another
process updates it?  Currently, with this bug, there's no
provision for this.

This is not a benign bug. it gives me the following problems: fror
instance, i do ESC . in my emacs to visit a tag-defn.  This emacs will
load TAGS (with view-mode on for me).  Then, if i am settng tAGS in
another emacs, this emacs first autoreverts TAGS and turns off
view-mode, but as the TAGS continue to get updated, it soon gives me
an error..
