What does the list_folders() method of mailbox.Maildir actually do (if anything)?

The Maildir++ spec states that folders need to begin with a period.
The list_folders method enforces that:
def list_folders(self):
"""Return a list of folder names."""
result = []
for entry in os.listdir(self._path):
if len(entry) > 1 and entry[0] == '.' and \
os.path.isdir(os.path.join(self._path, entry)):
result.append(entry[1:])
return result
The above example is from 2.6. Your structure is simply a list of
Maildir compliant directories below '/home/chris/Mail/apex.' They're
not, in the Maildir++ sense of the word, folders.
