When I originally wrote auto-revert mode I decided that Emacs should not
clear a buffer when the corresponding file was removed, as a safeguard
against a file accidentally being removed. Today, I still think that is the
correct way to handle this situation.
The current patch handles a special case when the file is removed after it
has been decided that it should be reverted, but right before the actual
revert -- it should be treated just like a normal file delete.
I think disabling auto-revert mode is not correct way to handle this -- the
file might be temporary removed by, say, a version control system and might
reappear a moment later, in which case we want it to be reverted into Emacs.
