Problem with horizontal ruler directly after fenced code section

When having a fenced code block directly followed by a horizontal ruler like:
```
~~~
B
~~~
---
```
we get the warning:
```
bb.md:5: warning: unexpected command endcode
```
due to the fact that the markdown parser replaces the `~~~` by a `@code` / `endcode` block and then handles the horizontal ruler `---` but this is seen as a level 2 header on the previous part resulting in the markdown code:
```
@page md_bb bb

@subsection autotoc_md0 @code
B
@endcode
```

The problem also occurs when a fenced code block is created with back tics.

By adding a `\n` this problem is fixed.
