bug#20943: 25.0.50; Dired buffers are not always auto-reverterd

[Mark Karpov]

***

I'm using ‘global-auto-revert-mode’ setting variable
‘global-auto-revert-non-file-buffers’ to t, like this:

  (setq global-auto-revert-non-file-buffers t)
  (global-auto-revert-mode                  1)

As far as I know, this is normal way to make Dired automatically
redisplay its buffer when contents of target directory are
changed. However, it doesn't always work. In some cases Dired buffer is
updated just fine, but there are also times when changes in target
directory don't cause redisplaying.

Is it a known problem? Can it be fixed? If it's a problem unique to my
machine (I doubt it, though) I can give your more information.
