These paths translate From_ lines into Return-Path: in unix style mailboxes.
If the mailbox is in MMDF format, it does nothing (since MMDF has already
done the Return-Path: translation while writing the message out.
WARNING: Do not merge these patches in with other patch files.
Keep them separate (Andrey, I mean you).

With old variant of this patch message size was counted incorrectly,
"rpath" variable can be referenced without initialization, second
Return-Path not skipped, fixed now.
