Same as before, would it be possible to restore the old copyright notice, so
this is counted as a "move" instead of "delete/add"?

Agreed, although I only saw 5 or files that failed this time, so maybe just
unchanging the notice on those files would suffice.

It's easy to do, so I restored them all and will make a follow-up CL with only
license changes.
