bug#13540: 24.3.50; Regression in trunk: auto-revert-mode fails on files accessed via samba

[Dani Moncayo <dmoncayo@gmail.com>]

Hello,

At work, I've just observed a regression in the trunk [1] wrt the
emacs-24 branch [2].

If I visit some file, say "t:\myfile" (where t: is a network unit,
mounted via samba, that points to an hp-ux server), and I enable
auto-revert-mode, the buffer is not reverted when some other program
changes the contents of the file.

The problem doesn't show up when the file is stored in a local unit
(c:\) but fails in the above case.

I've observed this bug in version [1], but not in version [2].
