[O] HTML export doesn't convert quote before footnote

[James Harkins]

This appears to be an HTML export bug: A straight double-quote mark before 
a footnote fails to convert into ”

Minimal example:

* Heading
Krusty the Klown opined, "Well, that's showbiz for ya."[fn:1]
* Footnotes
[fn:1] /The Simpsons/.

Expected:

<p>
Krusty the Klown opined, &ldquo;Well, that&rsquo;s showbiz for 
ya.&rdquo;<sup><a id="fnr.1" name="fnr.1" class="footref" 
href="#fn.1">1</a></sup>
</p>

Got:

<p>
Krusty the Klown opined, &ldquo;Well, that&rsquo;s showbiz for ya."<sup><a 
id="fnr.1" name="fnr.1" class="footref" href="#fn.1">1</a></sup>
</p>

I guess I can filter for it as a workaround.
