In autorevert-tests.el, the *Messages* buffer is narrowed systematically
prior any write-region call. I don't remember the details, but AFAIR
there were some other messages which have poisoned the tests.

I let it to you to change wherever you feel it is necessary. Tests will
show whether there are undesired side effects.

Best regards, Michael.
