Asciidoc, like markdown, is used by people writing blog posts. It would be great if it were able to ignore rendering the front matter of a file from being included into the preview. This is commonly done as

---
title: cool example
---
body content

or

+++
title: cool example 2
+++
body content

Ideally, the content inside the --- or +++ blocks would be ignored.
