Fix Javadoc typo for Spanned.SPAN_EXCLUSIVE_INCLUSIVE

    public static final int SPAN_EXCLUSIVE_EXCLUSIVE = SPAN_POINT_MARK;

    /**

     * Non-0-length spans of type SPAN_INCLUSIVE_EXCLUSIVE expand

     * Non-0-length spans of type SPAN_EXCLUSIVE_INCLUSIVE expand

     * to include text inserted at their ending point but not at their

     * starting point.  When 0-length, they behave like points.
