Forum:GREEN Updated since my last visit

When I look at the page history for an article, anything that is new since my last visit has the words updated since my last visit. In the Monobook skin, that phrase is highlighted in green. In the Oasis skin it is not. The green highlighting is very useful. So, I was wondering if anyone knows the JS/CSS to cause the same revision-history highlighting with the Oasis skin?
