In my configuration, your changes in article-hide-headers break
mml-preview.  edebugging `article-hide-headers' I get...

  edebug-signal:
  Buffer is read-only: #<buffer *Article nndraft:drafts*>

... at the following spot:

	    ;; Mark the rank of the header.
	    (put-text-property
	     (point) (1+ (point)) 'message-rank
	     (if (or (and visible (looking-at visible))
		     (and ignored
			  (not (looking-at ignored))))
		 (gnus-article-header-rank)
	       (+ 2 max)))

After evaluating the defun of `article-hide-headers' from gnus-art.el
7.42 doesn't show this problem.

Bye, Reiner.
