Yes, it works for inotify. And `file-notify-test04-file-validity-remote'
fails as expected, 'cos I haven't fixed it yet in Tramp.

For inotify it is obvious that it shall work. All inotify watches are
based on inodes. If a file is watched by inotify, and the parent
directory of the file is deleted, the inode of the file itself disappears.

I don't know how it works with w32notify internally. And I don't know
yet how it will behave with gfilenotify, all checks for that backend I
have moved to later.

Best regards, Michael.
