\201's back in 8-bit MIME parts

[Lars Magne Ingebrigtsen <larsi@gnus.org>]

The following new code in mm-decode.el seems to lead to the text being
decoded twice:

	    (if (eq (or (mm-handle-encoding handle)
			(with-current-buffer (mm-handle-buffer handle)
			  (mm-body-7-or-8)))
		    '8bit)
		;; Emacs MULE can not handle some 8bit characters in 
		;; multibyte character!!
		(let ((text (with-current-buffer (mm-handle-buffer handle)
			      (mm-with-unibyte-current-buffer
				(buffer-string)))))
		  (mm-with-unibyte-current-buffer
		    (insert text)))
	      (insert-buffer-substring (mm-handle-buffer handle)))

The `insert' up there into a multibyte buffer actually decodes the
text automatically (in Emacs 20.6, at least), so perhaps, er, some
variable or other should be bound to avoid having that done.
