Sieve \\Seen flag actions not replicated

[John Capo]

Tiring of running fixup scripts to keep seen state consistent, I
decided to find the problem.  In imap/lmtpd.c:

            sync_log_append(mailboxname); 
+        
+            if (nflags && user && !strncmp("user.", mailboxname, 5) && !strncmp(mailboxname + 5, user, strlen(user)))
+                sync_log_seen(user, mailboxname);
        }

The strncmps insure that the seen state is updated only for the
user that owns the mailbox.  Are they neeed?

Happy New Year!
