Thanks! I've fixed this in filenotify.el (in fact, the underlying watch
descriptor should not use quoted file names). Patch pushed to the branch.

In my interactive test, there was also another error:

--8<---------------cut here---------------start------------->8---
F files-file-name-non-special-handlers
    (ert-test-failed
     ((should
       (equal
        (find-backup-file-name nospecial)
        (mapcar
         (lambda ... ...)
         (find-backup-file-name tmpfile))))
      :form
      (equal
       ("/:/tmp/emacsqk0Dcl~")
       ("/:/tmp/emacsqk0Dcl.~1~"))
      :value nil :explanation
      (list-elt 0
                (arrays-of-different-length 19 22 "/:/tmp/emacsqk0Dcl~" "/:/tmp/emacsqk0Dcl.~1~" first-mismatch-at 18))))
--8<---------------cut here---------------end--------------->8---

I guess, it is because I have set `version-control' to t in my .emacs
(not investigated further).

Best regards, Michael.
