Subject: [PATCH] email: add signature delimiter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While this is created to match `himalaya`’s configuration API, this
could easly be reused for other programs that consume the email module
by concatination the strings.

(cherry picked from commit 05d71f517b6406471e2ebca49980db83e5c7d565)
