I think the right solution would be for send-email to move Date: to the
beginning of the body part, just like it adds an extra From: there when
the sender is different from the author, and not lie about the mail
transmission date.

Then we won't lose the authorship date information in the resulting commit
and will still keep the mailpath happy.
