Minor bug in MIME-PEM Interaction document

The examples in section 7 have a bug in their use of multipart:  there
is no boundary line before the first part, and there has to be.  In
other words, the bodies of each of the multipart/pem examples should
START with

--next-part

Not a major mistake, but you do want your examples to be legal MIME, right?

Other than that, I didn't see anything to object to in the document.  --
