Fix an example to make it fit the description
Fix an example to make it fit the description

As it is, the example would make `#content` from the response replace `#content` on the page, plus the other stuff.

I think the point of the example is to show how to replace multiple blocks of content, so I fixed it to make it do what the description says.
