Another case of fenced code block that should be handled

[LLyaudet]

Hello,

I saw the issue #53.

But nothing can be added to it since 2015.

And I thought that the following issue on gi-docgen would be of interest as a new test case:

https://gitlab.gnome.org/GNOME/gi-docgen/-/work_items/219

Below is the important part.

It is not mine, but a very useful comment by balooii.

Thanks, best regards, Laurent Lyaudet

This is what a regular code block returns:

import markdown

src = """\
Here comes a regular code block
```c
int x = 42;
```
"""
result = markdown.markdown(src, extensions=["fenced_code"])
print(result)

<p>Here comes a regular code block</p>
<pre><code class="language-c">int x = 42;
</code></pre>
<dl>

Now let's try your example: a code block within a definition list

import markdown

src = """\
`MY_CONSTANT`
:   Some description

    Here comes a code block within a definition
    ```c
    int x = 42;
    ```
"""

result = markdown.markdown(src, extensions=["def_list", "fenced_code"])
print(result)

<dl>
<dt><code>MY_CONSTANT</code></dt>
<dd>
<p>Some description</p>
<p>Here comes a code block within a definition
<code>c
int x = 42;</code></p>
</dd>
</dl>

Yeah, that looks not right. I would have expected this instead:

<dl>
<dt><code>MY_CONSTANT</code></dt>
<dd>
<p>Some description</p>
<p>Here comes a code block within a definition</p>
<pre><code class="language-c">int x = 42;
</code></pre>
</dd>
</dl>
