This is related to ``` not working properly. Relish has made some recent changes but this is broken. For this specific case, Relish was adding 2 format syntaxes. It converts ``` into `<pre><code>`. It was adding `class="bash"` to the `pre` tag, but `class="diff"` to the `code` tag. This resulted in a red highlighted diff code block.

For now, I put this here to prevent that. One Relish works out the MD issues, I will convert it back.
