1<p>Here's a simple block:</p>
2<p>&lt;div&gt;
3    foo
4&lt;/div&gt;</p>
5<p>This should be a code block, though:</p>
6<pre><code>&lt;div&gt;
7    foo
8&lt;/div&gt;
9</code></pre>
10<p>As should this:</p>
11<pre><code>&lt;div&gt;foo&lt;/div&gt;
12</code></pre>
13<p>Now, nested:</p>
14<p>&lt;div&gt;
15    &lt;div&gt;
16        &lt;div&gt;
17            foo
18        &lt;/div&gt;
19    &lt;/div&gt;
20&lt;/div&gt;</p>
21<p>This should just be an HTML comment:</p>
22<p>&lt;!-- Comment --&gt;</p>
23<p>Multiline:</p>
24<p>&lt;!--
25Blah
26Blah
27--&gt;</p>
28<p>Code block:</p>
29<pre><code>&lt;!-- Comment --&gt;
30</code></pre>
31<p>Just plain comment, with trailing spaces on the line:</p>
32<p>&lt;!-- foo --&gt;</p>
33<p>Code:</p>
34<pre><code>&lt;hr /&gt;
35</code></pre>
36<p>Hr's:</p>
37<p>&lt;hr&gt;</p>
38<p>&lt;hr/&gt;</p>
39<p>&lt;hr /&gt;</p>
40<p>&lt;hr&gt;</p>
41<p>&lt;hr/&gt;</p>
42<p>&lt;hr /&gt;</p>
43<p>&lt;hr class=&quot;foo&quot; id=&quot;bar&quot; /&gt;</p>
44<p>&lt;hr class=&quot;foo&quot; id=&quot;bar&quot;/&gt;</p>
45<p>&lt;hr class=&quot;foo&quot; id=&quot;bar&quot; &gt;</p>
