Re: bad copyright years

[Richard Stallman]

    The files who have copyright year before 1997 were released
    every year as part of Mule package.  They are integrated
    into Emacs in 1997.  And Emacs were released in 1997, 1998,
    and 1999.  So, perhaps I didn't have to add the year 2000,
    but I thought that having that year was not harmful.  And
    actually most files are modified in 2000 too.

It is ok.
