	* mm-decode.el (mm-dissect-buffer): Pass the from field on to
	`mm-dissect-multipart' and receive the from field as an (optional)
	argument from `mm-dissect-multipart'.
	(mm-dissect-multipart): Receive the from field as an argument and
	pass it on when we call `mm-dissect-buffer' on MIME parts. Fixes
	verification/decryption of signed/encrypted MIME parts.
