Preformatted text (<pre>)
Inside a <pre> tag, the spaces are conserved.
<pre>
Text in a pre element
is displayed in a fixed-width
font, and it preserves
both spaces and
line breaks
</pre>
By default, the converter renders them as a single table but you can turn this option off.
This is useful for piece of code like what you see in the blog nowadays.
converter.RenderPreAsTable = false;
