Emacs is not notified, when a file changes its state outside Emacs. Only
prior to writing to a file Emacs checks, whether a file has changed on disk.
The upcoming Emacs 24.4 has implemented file notifications on systems
which support it (mainly GNU/Linux and MS Windows). This could be used
for this kind of checks.
For Emacs 23, I don't regard this as a bug.
Best regards, Michael.
