Although we watch the parent directory internally (except with kqueue),
the given scenario by Tassilo shall work as he expected. There shall be
two file notification events in the given case, calling
magit-filenotify--callback and auto-revert-notify-handler with the
respective descriptor.

I'll check.

Tassilo, would you be willing to write an ert test case for the problem?

Best regards, Michael.
