If the message has actually been resent twice there should be a
Received: header between the sets of Resent- headers.

Although it's horrible from the point of view of history and practice,
I think RFC 2822 is reasonably clear about the intended behaviour.
See the syntax for "fields" on page 18, which states that Resent-
headers are to be interleaved with Received: headers. I think Pine
is working to an older more ambiguous spec.

It does to me. Received headers are prepended and appear from newer to
older as you read down.

A block here means a set of Resent- headers and the associated
Received: lines. e.g.
Received: from draco.cus.cam.ac.uk ([131.111.8.18])
by red.csi.cam.ac.uk with esmtp (Exim 4.20)
id 135709-000000-00
for fanf2@???; Tue, 11 Nov 2003 13:57:09 +0000
Resent-Date: Tue, 11 Nov 2003 13:57:09 +0000
Resent-From: Philip Hazel <ph10@???>
Resent-To: Tony Finch <fanf2@???>
Message-ID: <E135709-000000-00@???>
Received: from [193.201.200.170] (helo=chiark.greenend.org.uk)
by draco.cus.cam.ac.uk with esmtp (Exim 4.20)
id 123456-000000-00

From: Tony Finch <dot@???>
To: Philip Hazel <ph10@???>

Subject: example
blah
The first block is the first four header fields, the second is the fifth
header field.
