Read what I said.  The preferred style is 2002-2009, and that's the
strong recommendation for people to follow unless there's a compelling
reason to differ.

Some of the "edge" cases have been listed in this thread:
(1) Work that's done to the same file, both on your own, and for
    clients who own the work.
(2) Interaction with external projects.
(3) Strong developer preference for listing years.

Listing the years provides extra data, but doesn't give any extra
legal strength.
