Argh. I'll be less careless in the future, I promise.

I had concluded that scanning the original directory was odd but
better because it served to double-check that all the original files
actually made it and also because if there were any unrelated files
present there was no need to fsync them. But I agree it's odd and not
very general for copydir if we decide to use it elsewhere other than
create database.
