Here the thing to remember is that block level structure indications
take precedence over inline level structure indications:

```
% pandoc
Term
: Def
<!--
: comment def
-->
^D
<dl>
<dt>Term</dt>
<dd>
Def &lt;!–
</dd>
<dd>
comment def –&gt;
</dd>
</dl>
```

```
% pandoc
Term
: Def
test <!--
: comment def
and -->
^D
<dl>
<dt>Term</dt>
<dd>
Def test &lt;!–
</dd>
<dd>
comment def and –&gt;
</dd>
</dl>
```

```
% pandoc
Term
: Def
`code
: comment def
more code`
^D
<dl>
<dt>Term</dt>
<dd>
Def `code
</dd>
<dd>
comment def more code`
</dd>
</dl>
```
