No query at autorevert

["Florian Kaufmann" <sensorflo@gmail.com>]

Hello

I try to enable the global auto revert mode. But I'd like XEmacs to ask
me whether it should really revert a buffer in the case it detects that
the file on disk has changed. So I wrote in my init.el file
(global-auto-revert-mode 1)
and in my custom.el file
(custom-set-variables
  '(revert-without-query (quote (""))))

Now auto revert works, the buffers are reverted if they are changed
outside XEmacs, however I never get queried if i really want to revert
the buffer. Any ideas?

Thank you

Flo
