Comment span class for lua is 'do', not 'co' as I would expect

[larryhynes]

Hi

The following example:

~~~lua
-- Comment
~~~

~~~sh
# Comment
~~~

~~~rust
// Comment
~~~

~~~c
/*
 * Comment
 */
~~~

yields the following output:

<pre class="sourceCode lua" id="cb1"><code class="sourceCode lua"><div class="sourceLine" id="cb1-1" data-line-number="1"><span class="do">-- Comment</span></div></code></pre>
<pre class="sourceCode sh" id="cb2"><code class="sourceCode bash"><div class="sourceLine" id="cb2-1" data-line-number="1"><span class="co"># Comment</span></div></code></pre>
<pre class="sourceCode rust" id="cb3"><code class="sourceCode rust"><div class="sourceLine" id="cb3-1" data-line-number="1"><span class="co">// Comment</span></div></code></pre>
<pre class="sourceCode c" id="cb4"><code class="sourceCode c"><div class="sourceLine" id="cb4-1" data-line-number="1"><span class="co">/*</span></div>
<div class="sourceLine" id="cb4-2" data-line-number="2"><span class="co"> * Comment</span></div>
<div class="sourceLine" id="cb4-3" data-line-number="3"><span class="co"> */</span></div></code></pre>

Note that in the output each language's comments, with the exception of lua's, are given the span class co. (I have always assumed that was shorthand forcomment.)

Did lua's comment syntax change, or is this expected behaviour from skylighting, or should I be making my enquiries upstream of you?

(It should be noted that I'm using pandoc, not skylighting standalone, so as per this issue I'll stop making noise here.)
