[Dovecot] Still weird UID ordering issues with maildir

[Jeff A. Earickson]

Hi,
While I am using mbox instead of maildir, I've noticed similar
weirdness.  I'm using 1.0alpha2 on Solaris 9 (since last night). 
I connect to imap with Pine 4.63.   My mailbox is NFS mounted 
to the IMAP server from our mail server (Solaris 9 for both boxes).

If I delete large numbers of messages and then my pine message
list screen refreshes (via eXpunge) then sometimes my message
numbering is off by one.  After the expunge, if I move to message
67 and open it, dovecot will show me message 68 instead.  The
only way to fix this is to close pine (and the imap connection)
and restart.  This off-by-one error most often happens while I am
deleting messages and a new message arrives.

An annoyance, but I never had this problem with UW imap.
