dsync confusion

[dovecot at chubb.wattle.id.au]

Hi Folks,
   The man page for doveadm-sync says that the final argument is the
   destination to which files will be written.

   But the example later in the man page says the opposite.
   Under 'Conversion' I read:

      ```
      Assuming that the mail_location setting in
      /etc/dovecot/conf.d/10-mail.conf is set to:
          mail_location = mdbox:~/mdbox,
      a logged in system user may convert her/his mails
      from its Maildir in her/his home directory to the mdbox mailbox
      format.  The user has to execute the command:

              doveadm sync maildir:~/Maildir
      ```

   which has the destination in /etc/dovecot/conf.d and the _source_ as
   the final argument to doveadm sync.


   It seems on trying it, that the example doesn't work.
   To convert from, say mbox to Maildir, I had to do:
     doveadm backup 'maildir:~/Maildir:LAYOUT=fs'
   with /etc/dovecot containing
     mail_location = mbox:~/Mail/:INBOX=/var/mail/%u:INDEX=/var/indices/%u


   Even this didn't work properly for me.  All the messages from all
   the mboxen in ~/Mail ended up in ~/Maildir/cur and the other mailboxes
   ended up with empty cur/ and new/ directories under ~/Maildir/xxx/

   Dovecot version 2.3.19.1 (9b53102964)
   installed from Debian sid on x86_64.
   Home directories are NFS mounted.
   I don't think the rest of the config is relevant.
