  // First, make sure that none of the .info files have a change time newer
  // than the last time we checked for available updates. If something was
  // changed, it almost certainly means a new version was installed. Without
  // fresh data, the logic in update_status_calculate_project_data() will be
  // wrong and produce confusing, bogus results.
