inotify.7: Clarify with events are generated for watched directories

Really, with respect to watched directories, events fall into
three classes (not two, as was shown):

* Events that can be generated only for the watched directory.
* Events that can be generated only for objects that are inside
  the watched directory.
* Events that can be generated both for the watched directory
  and for objects inside the directory.

So, mark these three classes more clearly in the list of inotify
events.
