    Use years range in copyright notice
    
    From GPL howto:
    
    For software with several releases over multiple years, it's okay to
    use a range (“2008-2010”) instead of listing individual
    years (“2008, 2009, 2010”) if and only if every year in the range,
    inclusive, really is a “copyrightable” year that would be listed
    individually; and you make an explicit statement in your
    documentation about this usage.
