nnrss parses < twice.

Hi guys!

Small problem here with the nnrss backend.  If you have a RSS feed that
uses some < or > in the *text* (as opposed to the HTML code), those will
be parsed, and w3m (if you use w3m) will screw up badly.

Such RSS feed will have an entry like :

   When &lt;strong&gt;Mickey&lt;/strong&gt;'s colleague was tasked with
   changing &amp;lt;br&amp;gt;s

which should result in HTML in


   When <strong>Mickey</strong>'s colleague was tasked with changing
   &lt;br&gt;s

and in the final reading in

   When *Mickey*'s colleague was tasked with changing <br>s

Problem is, this field is « HTML-unescaped » twice :

- On line ~456,

	  (setq xmlform (xml-parse-region (point-min) (point-max)))

because xml-parse-region uses xml-parse-string which uses
xml-substitute-special.

- On line ~772,

          (and extra (nnrss-decode-entities-string extra))

which uses mm-url-decode-entities-nbsp.


This leads to the <br> being interpreted as a newline.


I don't know if `w3-parse-buffer' does the same, but as xml-parse-region
works for all my feeds, I use the following change :

Let me know if I should install it.
