Subject: [PATCH] Pass extra parameter to children of multipart/alternative
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A structure like this is quite common:

  ─><no description>                    [multipa/related, 7bit, 12K]
   ├─><no description>              [multipa/alternativ, 7bit, 9.0K]
   │ ├─><no description>      [text/plain, quoted, iso-8859-1, 3.7K]
   │ └─><no description>       [text/html, quoted, iso-8859-1, 4.9K]
   └─>2b0063.jpg                          [image/jpeg, base64, 3.3K]

Here the main content of multipart/related isn't the html part, but a
multipart/alternative containing the html part and a text part. The html
part still needs access to the onther content of the multipart/related
part, so we need to pass this through.
