Check the ok before reading from the event. Essentially, this needs to happen before line 27.

Same as above, check for close before reading the error. :)

This PR is just about adding a check for closed channels to the example https://github.com/fsnotify/fsnotify/blob/master/example_test.go
Without that check the goroutine will keep printing empty errors (nils) & events after the watcher is closed.
See #229
