autorevert doesn't change mode-line-modified anymore

[Klaus Zeitler]

autorevert behavior has changed recently. When I move (outside the emacs
session) a write-protected file to a readable file, that I have in an emacs
buffer, (and vice versa) emacs autoreverts the file contents, but doesn't
update the variable  buffer-read-only anymore, i.e. the read-only status
remains the same. In emacs 21.2 the read-only status was updated correctly.

The call to revert-buffer in auto-revert-buffers moved recently to
auto-revert-handler and was encapsulated with a let statement:
  (let ((buffer-read-only buffer-read-only))
    (revert-buffer 'ignore-auto 'dont-ask 'preserve-modes))

What was the reason for this change?
