Review comment:
Unless I'm missing something (I've only had a _quick_ look) I think we
should be able to do this as something like:
```python
def run(self):
_, filename = self.env.relfn2path(self.arguments[0])
retnode, = super().run()
container_node = nodes.container("", literal_block=True,
classes=["example-block-wrapper"])
container_node += example_header(filename=filename)
container_node += retnode
retnode = container_node
return [retnode]
```
