Thanks.  It is not for the archives' sake; I do not take (or notice
in the first place) patches in attachments, simply because rarely
anybody reviews attachments.

When you are sending the patch in for real, after making a non-patch
discussion (all of the above), you can write a "scissors" line

----- >8 -----

right here, immediately before your "From:" and "Subject:".  What it
does is to tell "git am" on the receiving end to ignore everything
it saw up to that point and pretend the message starts there.

You do not want to include "From <object name>" line that is used as
an internal separator in the mailbox format.  You do not want to
include the "Date:" in-body header, either.  "From:" and "Subject:"
are used often because they are frequently different from the e-mail
(e.g. in the message I am responding to, the sender is rjuju123@gmail,
not julien.rouhaud@free.fr, and we want the latter on the From: line
because that is what appears on the Signed-off-by: line).

Thanks.  Will queue.
