`-x fenced_code` does not provide proper highlighting

[venthur]

Hi,

I want to write a presentation with code examples using fenced code blocks. That means instead of writing

!python def foo(): pass

I want to use the (more common) fenced code blocks:

def bar():
    pass

According to the docs darkslide supports the extensions provided by the python markdown library, but running

$ darkslide -x fenced_code slides.md

Produces proper python styling for the first example but unstyled

<pre><code class="python">def bar():
    pass
</code></pre>

for the second.
