         * The point of this TextWatcher is that when the user chooses
         * an address completion from the AutoCompleteTextView menu, it
         * is marked up with Annotation objects to tie it back to the
         * address book entry that it came from.  If the user then goes
         * back and edits that part of the text, it no longer corresponds
         * to that address book entry and needs to have the Annotations
         * claiming that it does removed.
