Re: Adding missing copyright years

[Richard Stallman]

    What if 10 lines get changed in each year of (say) 2000-2005
    inclusive? Each year, the changes are too small to be substantial. But
    the net result is that the state of the code in 2005 differs
    substantially from that of 2000 (by 60 lines in this example). How is
    the copyright header supposed to deal with this kind of gradual,
    cumulative change?

In such a borderline case, if we put down just 2005, it would not
be wrong.
