Any reason for no syntax highlighting in styleguide.md?

In your style guide, you have code snippets for some Java code, but no syntax highlighting (e.g. [in the indent section](https://github.com/twitter/commons/blob/master/src/java/com/twitter/common/styleguide.md#indent-style)). Is there a reason why you're using `:::java` instead of ` ```java`?

If not and you would prefer to have syntax highlighting, I'd be happy to edit the style guide.
