Because you need to exclude 1981, 1982, 1984, 1985, 1987 and 1990
which are missing in list of years. :-)

Copyright counts for published years. Look at the copyright on a book that's not a first edition, try classic children's books. They'll list several years decades apart. If nothing was published in 1983, there's no new copyright for that year. In 2077, what was released in 1982 will be public domain, and nothing more until 2079.

    There's that, also that copyright message belongs to the Regents of
the University of California and unless I misremember one of the license
conditions is retaining their copyright notice - altering it would
probably
be a license violation.


It seems the regents copyright claims end in 1994. Perhaps some
underlying piece of code is still in FreeBSD requiring this notice?


Perhaps the creation of FreeBSD and the release of 4.4BSD? Nothing from Berkley's been added, so no new copyright. There's little need to incorporate later patches to 4.4BSD because divergences between the 4.4BSD and FreeBSD.
