I fear this is not sufficient. This patch handles only file
notifications which are implemented via tramp-sh.el.

Yesterday, I have committed a patch which adds
`tramp-gvfs-handle-file-notify-add-watch' (using gvfs-monitor-file to
poll for changes on GVFS mounted directories).

Maybe we rethink to introduce `file-notify-supported-p' and its
handlers?

Best regards, Michael.

electronic devices on board".
