[O] Another HTML Export Problem

[Scott Randby]

Some links are not exporting properly with org release_7.5.52.g0dc16. It
seems that any link that contains "&" does not export correctly. Take
the four links given below.

[[http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&id=xetex][XeTeX]]

http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&id=xetex

[[http://www.casio.com/products/Calculators_&_Dictionaries/][Casio]]

http://www.casio.com/products/Calculators_&_Dictionaries/


These links are incorrectly exported by version 7.5 as:

<p>
@&lt;a
href="http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&amp;amp;id=xetex"&gt;XeTeX</a>
</p>

<p>
@&lt;a
href="http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&amp;amp;id=xetex"&gt;http://scripts.sil.org/cms/scripts/page.php?site<sub>id</sub>=nrsi&amp;amp;id=xetex</a>
</p>

<p>
@&lt;a

</p>

<p>
@&lt;a
href="http://www.casio.com/products/Calculators_&amp;amp;_Dictionaries/"&gt;http://www.casio.com/products/Calculators<sub>&amp</sub>;amp;<sub>Dictionaries</sub>/</a>
</p>

With version 7.4, the links are correctly exported as:

<p>
<a
href="http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&amp;id=xetex";>XeTeX</a>
</p>

<p>
<a
href="http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&amp;id=xetex";>http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&amp;id=xetex</a>
</p>
