Well...  The whole point is that I need to pass multi-language text in
strings (TM expects to be able to do so -- it was designed for Mule).
I can do this with text properties (or extents), but not, as far as I
know, with overlays.

Right now, I've simply overridden the defalias in gnus-vis.el with

(defun gnus-put-text-property (start end property value &optional object)
  (if (and (eq 'face property)
           (text-property-not-all start end 'face nil))
      nil
    (put-text-property start end property value object)))

and everything seems to work.  Or is this evil in any way (except
insofar as mucking around with L.I.'s code is blasphemy, of course)?

P.S. So I'm reading this message by NNTP from Denmark, replying
through SMTP to Norway...  I have some problems grasping this Internet
thing, somehow.
