One nice feature of [Prism.js](http://prismjs.com/plugins/line-highlight/) is a plugin to highlight specific lines. A really nice use case can be seen in [Dive Into Python 3](http://getpython3.com/diveintopython3/your-first-python-program.html#everythingisanobject). I think [Tokens#split_into_lines](https://github.com/rubychan/coderay/issues/63) will make it possible to do this in an (external) extension.
