Auto Trim w/ Erubis (Rails 3.0 beta)

Hey, I’m relatively new to Rails. (I was actually a Merb guy before)
and I’m getting my feet wet with the beta.

It doesn’t appear that auto trim is enabled with Erubis by default.
What’s the “proper” way to enable this?

In case anyone else cares… looks like this is a bug and doesn’t work
quite right.
