Your system is clearly doing something else there and it is very
strange. I just replicated the above configuration and here it did
what everyone would expect: it inserted all those X-headers into the
mail headers and loaded the text editor. That *included* the
Pratchett one. Which is where they stay when the message is sent
(user-agent being appended, of course).
How that last custom header gets moved from being a proper header into
the MIME part header is the main thing to look at. It could be
something with whatever text editor is used or it could be some script
running on the message after it's saved, but before it is sent. I
suspect the latter since the change must be made after the signature
is made, since that would explain why editing your messages to remove
that line then makes the messages verify.
