Bug in copyright-update

[Bingham, Jay]

In Emacs 21.3 the documentation for copyright-update (in copyright.el)
states:
If optional prefix ARG is given replace the years in the notice rather
than adding the current year after them.

However his is not what occurs, instead the word copyright is deleted
and replaced with the current year.

The offending sexp is:
(delete-region (match-beginning 1) (match-end 1))

It should be:
(delete-region (match-beginning 2) (match-end 2))
