* Add ability to set In-Reply-To tag
This is useful to reply to a specific email, e.g. to a patch sent by
email on a mailing list.
Please note that both the In-Reply-To and the References tags are
filled-in. In theory, only the In-Reply-To tag should be enough but they
are both linked to the same idea and in theory most emails readers
should support a Message-ID given in In-Reply-To tag. So just in case,
we fill both to imitate many email clients.
