I did try this when I first implemented it, as it's a much neater 
solution to the problem. Unfortunately a lot of mail clients didn't play 
well with that idea, so I had to resort to the current solution of 
inserting the signature in the most likely MIME parts of the message. 
This is a pain as it breaks cryptographic signatures of the MIME parts, 
but it's the only way most mail clients will display correctly. And a 
lot less the half the people in the world use cryptographic signatures 
of email messages, so they lost out to the majority. If you want crypto 
sigs to work, just turn the feature off :-)
