- Moved the checkout of the cvs source above the version prompting so

that we can use the version from the configure.in file to provide
  good default values for the user.
- When moving old tar/diff files into the old-* dirs, first hard-link
  them into place, then (if "live"), use rsync to update these new
  files on the server (which saves us later re-sending), and _then_
  delete the old names.
