fences

1. A fence indented three spaces under a list item:

{{include lib/snippets/never.md}}

A tilde fence:

~~~
{{include lib/snippets/never.md}}
~~~

A backtick fence closed by a longer run:

{{include lib/snippets/never.md}}

A tilde fence that a backtick line does not close:

~~~markdown
```
{{include lib/snippets/never.md}}
```
~~~

{{include lib/snippets/real.md}}

Only the last directive is outside every fence.
