[PATCH 3/3] CLI/new: support maildir synced tags in new.tags

[David Bremner <david@tethera.net>]

We reorder reading maildir flags to avoid overwriting 'new.tags'. The
inverted status of 'unread' means the maildir flag needs to be checked
a second time.

I backpedalled here on the idea of supporting 'new.tags' without
'unread' in the presence of maildir syncing.  For files in 'new/', it
seems quite natural to tag them as 'unread'.
