In recent copyright.el I noticed copyright-update using the match data
after a y-or-n-p query.  Is that a good idea?

When running it in emacs 22 I seemed to sometimes get the match data
clobbered by y-or-n-p.  I never tracked down the circumstances, but
wondered if copyright.el shouldn't rely on what an input func like
y-or-n-p could do, per diff below.
