This looks like modified by John himself back in Fri Apr 18, 2003 so let
ask him if he remembers. The commit faf2600 don't help much.

Hi John,

To be brief, there's a treatment we'd like to understand why it's there.
The offlineimap/repository/LocalStatus.py file has

  def getfolderfilename(self, foldername):
      foldername = re.sub('^\.$', 'dot', foldername)
      return os.path.join(self.directory, foldername)

We understand that "." directores may be a problem but did you hit this
case or did introduce it to be safe?

We may change behaviour to ignore/skip such foldername and warn.

Thanks.
