[offlineimap] Removal of "maxage" for imap-to-imap sync in 6.5.7 causes duplication of messages on sync (#242)

[Lars Möllendorf]

nicolas33: Yes, you are right. I mixed up syncing the cache with the actual
state of the Maidir and syncing of the data held in RAM to the file system.

I tried to sync between IMAP and Maildir without success.

Before syncing with offlineimap I had these folders in Maildir:

```
.ads
.archive
.drafts
.forums
.providers
.sent
.support
.trash
.webshops
cur
new
tmp
```
After syncing with offlineimap I get this folders:

```
.
..
.ads
.archive
.drafts
.forums
.providers
.sent
.support
.trash
.webshops
INBOX
Postausgang
cur
drafts
maildirfolder
new
sent
subscriptions
tmp
trash
```

I don't know where the folders "maildirfolder" and "subscriptions" come from.
Maybe the e-mail provider added those.

Additionally I get this errror:

```
$ offlineimap -c /home/user/offlineimapfiles/offlineimaprc.hermes

```

This is my config:

```
[general]
accounts = hermes at whatever.org
maxsyncaccounts = 6
status_backend = plain
ui = TTYUI

[Account hermes at whatever.org]
localrepository = hermes at whatever.org-Local
remoterepository = hermes at whatever.org-Remote

[Repository hermes at whatever.org-Local]
type = Maildir
localfolders = "/home/user/Maildir/hermes at whatever.org"
maxage = 720
nametrans = lambda foldername: foldername.replace('drafts', 'Entwurf').replace('trash', 'Papierkorb').replace('sent', 'Gesendet')

[Repository hermes at whatever.org-Remote]
type = IMAP
remotehost = imap.whatever.org
remoteuser = hermes at whatever.org
ssl = yes
remotepassfile = ~/offlineimapfiles/Password.IMAP.hermes at whatever.org
nametrans = lambda foldername: foldername.replace('Entwurf', 'drafts').replace('Papierkorb', 'trash').replace('Gesendet', 'sent')
```

And here are my questions:

* Can I tell offlineimap to respect the existing dovecot Maildir structure and use leading dots for the mail folders?
* What does the error message mean? Is offlineimap misinterpreting the leading dots of the mail folders and trying to create a root folder ('/') ?
