[Dovecot] The Status: header is forced

[Olivier Tharan]

	Hi,

I started testing dovecot for our next POP/IMAP server (nearing
production state), and noticed that the Status: header is always
added, with a value of 'O' or 'RO'. This happens in
`lib-index/mbox/mbox-rewrite.c'. This does not seem to happen in
the Maildir case.

Is the Status: header really needed in every case? This breaks
mutt which displays mails with a 'O' flag instead of 'N'.

My dovecot is 0.99.10.4 (FreeBSD port), but the behavior is still
the same in the CVS version.
