Parse unpaired quotations

[garry.yao]

Editor will not parse the following source, degrade it into a single text node, some fault tolerant has to make instead.

<span style=""">text</span>

[j.swiderski]

Safari, FF3 produce (in my opinion) the correct code:

<span style="">text</span>

Opera, FF4 and Chrome produce:

<p>&lt;span style=&quot;&quot; &quot;=&quot;&quot;&gt;text</p>

All versions of IE produce:

<span>text</span>
