IANAL, but from 2 discussions with copyright-clerk:

  1. We start claiming copyright the year the file as committed
     to a medium (hard drive), not the year it was published.

  2. As long as we have evidence of a copyrightable change each year,
     we can include that year in the list of copyright years in
     all files' headers.

For (2), this is how I asked the FSF:

... to which they answered that it would be acceptable.

Does it mean that the sources needed to be made public that year for
us to be able to claim copyright that year? It did not seem so to me.
But you could ask the FSF (copyright DASH clerk AT fsf DOT org).
