Subject: 24.3.50; auto-revert-mode does not revert upon invocation
Date: Thu, 04 Apr 2013 20:08:00 +0200

In a shell:
$ echo hello > foo
$ emacs -Q foo &
$ echo bye > foo

In Emacs:
M-x auto-revert-mode

<the buffer keeps showing "hello">

In the past, after executing auto-revert-mode the buffer was reverted to
the file's current contents. Nowadays, the buffer keeps showing the
file's old contents until the file is modified again.

This is obviously a bug because an unmodified buffer with
auto-revert-mode enabled is supposed to show the current contents of its
associated buffer.
