Unreliable code block rendering

[georgeedwards]

I have two code blocks in my markdown string. This doesn't parse properly:

```bash
tns platform add ios
```

However, this one does:

```bash
cd sample-Groceries
```

These are the two results:

<code>bash
tns platform add android</code>

<pre><code class="lang-bash">cd sample-Groceries
</code></pre>

They are both in the same string, processed at the same time of the same machine...

Here you can see the whole file, markdown and html

I have no problem parsing both. Provide your complete source please.

I have a similar issue using v0.3.6, for example:

<h1> H1 </h1>
<h2> H2 </h2>

```html
<h1> H1 </h1>
<h2> H2 </h2>
``` 
<h1> H1 </h1>
Some content

Would produce:

<h1> H1 </h1>
<h2> H2 </h2>

<code>html
&lt;h1&gt; H1 &lt;/h1&gt;
&lt;h2&gt; H2 &lt;/h2&gt;</code>

<h1> H1 </h1>

<p>Some content</p>

But if you add a matching h2 after the code block:

<h1> H1 </h1>
<h2> H2 </h2>

```html
<h1> H1 </h1>
<h2> H2 </h2>
``` 
<h1> H1 </h1>
<h2> H2 </h2>

Some content

The problem goes away and you'll get a correct code block:

<p><h1> H1 </h1></p>
<h2> H2 </h2>

<pre><code class="lang-html">&lt;h1&gt; H1 &lt;/h1&gt;
&lt;h2&gt; H2 &lt;/h2&gt;
</code></pre>
<p><h1> H1 </h1></p>
<h2> H2 </h2>

<p>Some content</p>
