Are you sure about that? It sounds quite technical. But if you think it
is necessary, I'll add it.

The revised patch now excludes such non-file buffers. I wonder if
buffers with file names should be excluded as well. They trivially
occur when visiting a file whose name starts with a space.

The new patch also has the tracking variable renamed to
`auto-revert--global-mode' and added a new hook,
`after-set-visited-file-name'; the advice calls are gone.
