[Mimedefang] HEADS UP, bug in spamassassin versions 2.50 -> 2.63

[Chris Myers]

Here's the patch again, as an attachment.  Hopefully this will help folks
experiencing text-wrapping problems.

This patch is against SpamAssassin 2.64, but can also be applied against
version 2.63 (patch will report that a hunk succeeded at an offset of -42
lines).
