    The way I read his original post, he was trying to account for the fact that
    some mail clients re-wrap the lines before sending, effectively re-ordering
    the characters and destroying any signature that you might compute. What's
    worse, the line-length is usually user-adjustable, thereby negating any
    possibility that you might hack around it.

    There are several kluges around this problem that have been enshrined in
    RFC's. The most general solution is to create the encrypted, signed,
    encoded message and then send it as an attachment or as a new mime-type.
