I don't usually bump up version numbers across all source files wholesale. It don't know that it hurts anything, but unless the file has actually changed, in what sense does its copyright date need to be updated?

I'd be in favor of removing the file-level copyrights. But as long as they're there, I figure might as well update all to account for all recent changes.
