It's not just being qeasy. It is a design rule, that advising functions
do not belong to core Emacs.

There is `find-file-hook'. If we need to hook into
`set-visited-file-name', we shall create a new hook
`after-set-visited-file-name', and run it there.

Somehow, I'm not so comfortable with that name. Could we take
`auto-revert-global-mode'? It is similar to `auto-revert-mode' and
`auto-revert-tail-mode', with the disadvantage that there does not exist
such a mode.
Alternatively, we could create a local variable `global-autorevert-mode'
in buffers which are tracked, and check always for that local value
where it matters.

These are almost identical. Make argument buffer optional, and it is
just one function.
Best regards, Michael.
