Code blocks within list items should be code-blocks

[kylef]

Code-blocks within list items (i-e, blocks that are indented by 4 spaces inside a list item) are not marked as code blocks, so underscores and other markdown syntax still work and cause the code not to be rendered correctly.

Example

+ Model (application/json)

        {
            "_id": "963bc95f1c1a56f69f3392b4aa03302f",
            "foo": "_bar"
        }

Any change this can be addressed? It makes it very annoying to work with hal+json or anything that has an underscore
