Subject: Re: [PATCH] send-email: restore --in-reply-to superseding behavior

a test case in t/t9001-send-email.sh will also help, as I am not sure
this might be "expected behaviour" as hinted in the man page for
git-send-email (under --thread):

"It is up to the user to ensure that no In-Reply-To header already exists
  exists when git send-email is asked to add it (especially note that
  git format-patch can be configured to do the threading itself).
  Failure to do so may not produce the expected result in the
  recipient's MUA."
