examples/unmarked: fix markup

[jamesmunns]

This layout was actually intentional. I was noting that the bullet list "belongs" to the line immediately above. Is this not acceptable markup syntax?

Poor description, sorry ;)

The change is based on the differing output markdown produces.

$ markdown ../examples/unmarked/marketing-requirements.md
<h1>User Interaction</h1>

<p>The product will support English and German Languages</p>

<p>The product will count to a user-defined number sequentially</p>

<h1>Compatibility Requirements</h1>

<p>The product will be written in <a href="http://foo.html">Python3</a></p>

<h1>Functional Requirements</h1>

<p>The product will greet the user as such:
* Hello!
    * (No Comma)
* World!</p>

versus (this PR):

$ markdown ../examples/unmarked/marketing-requirements.md
<h1>User Interaction</h1>

<p>The product will support English and German Languages</p>

<p>The product will count to a user-defined number sequentially</p>

<h1>Compatibility Requirements</h1>

<p>The product will be written in <a href="http://foo.html">Python3</a></p>

<h1>Functional Requirements</h1>

<p>The product will greet the user as such:</p>

<ul>
<li>Hello!
<ul>
<li>(No Comma)</li>
</ul></li>
<li>World!</li>
</ul>

Environment:

$ markdown -v
