add hack-a-round for language specified markdown code blocks
When language is specified in a markdown code block such as:
````
```c
printf("Hello, world!\n");
```
````
is used, the resulting HTML as produced by `pandoc(1)` combined
with our revised `ioccc.css` is not intent the code block well.
A temporary "_hack-a-round_" is to turn the "markdown code language
specifier" into an HTML comment. For example:
````
```<!---c-->
printf("Hello, world!\n");
```
````
This commits turns off existing markdown code language specifiers
for now, while preserving our ability to restore them in the future
when a better "_hack-a-round_" to the "markdown code language
specifier" problem is found.
The HTML impact if this "_hack-a-round_" is to produce HTML that
looks like this:
```
<pre class="<!---c-->"><code> .. </code></pre>
```
We might be able to create a complex set of classes for each markdown
code language (there won't be very many) in `ioccc.css`, or we might
find a more general CSS (or maybe `pandoc(1)`?) solution.
For now, this hack-a-round will have to do.
