So we must document in the Elisp manual, that buffers, which want to
participate in global-auto-revert-mode after a renaming, shall change
the name via set-visited-file-name.

Agreed. Those buffers are special (internal) anyway, it's already tricky
to show them. Nobody needs auto-revert for invisible buffers :-)

D'accord.

But they will convert to hook functions then ...

Best regards, Michael.
