Subject: [PATCH] Implemented some of Enhanced Ordered Lists: numerically
 ordered lists now start with the first number given.  For example, if you
 start your list in Markdown as follows:

2. second list item
3. third list item

then Markdown will produce this:

<ol start="2">
<li>second list item</li>
<li>third list item</li>
</ol>
