We'll prepend Resent: headers though .. that should be enough

That's not permitted by RFC 2822 and it'll cause interoperability problems
with software that only implements RFC 822 Resent- semantics (only one
group of Resent- fields). AFAIK most software that understands Resent-
fields does not understand RFC 2822 multiple Resent- groups.
