When sep='/' in a Maildir, we were doing a os.path.join(dirname,'') on the top level maildir, which results in a "dirname/", so all our maildir folder names had slashes appended. Which is pretty much wrong, so this fixes it by only using os.path.join when we actually have something to append. Signed-off-by: Sebastian Spaeth <Sebastian@SSpaeth.de>
