The problem is telling which is an import branch, since it currently
just used "refs/heads/<branch>".

I do have a change to write the timestamp to a file, which takes the
newest commit across all of the branches that have changed during an
import.  That may well be good enough but doesn't let you incrementally
update a repository that has been cloned from elsewhere.
