merge: report non-interactive progress in chunks
Instead of a monotonic count, getupdates yields the number of files it
has updated since it last reported, and its caller sums the numbers when
updating progress.
Once we run these updates in parallel, this will allow worker processes
to report progress less often, reducing overhead.
