Calling file-notify-rm-watch on an invalid descriptor may throw a
invalid-function error, but it should throw a file-notify-error instead.
For example, this may occur when calling the function multiple times on
the same descriptor.
The error stems from file-notify--rm-descriptor, which contains the expression
(funcall
(cdr (assoc file (cdr registered)))
`(,descriptor stopped ,(if file (expand-file-name file dir)
dir)))
, but (assoc file (cdr registered)) is nil. I think this error is
confusing.
Attached you'll find a test case for this.

`file-notify-error' shall appear only from `file-notify-add-watch'.
`file-notify-rm-watch' shall not raise an error at all.

I've fixed this in the master branch; there shouldn't be an error anymore.

Thanks also for this. I've added it, modified, to filenotify-tests.el.

Nobody reported that this doesn't work, so I'm closing the bug.
