Error in render example

[codegangsta]

In the section "Using the render package," the render call using the example template doesn't do what you would expect.

Specifically, by passing "nil" it will not render anything in the {{.}} bit. This was pretty easy for even a "go-newbie" to figure out, but then again I have a lot of non-Go programming experience. It might be confusing to an overall beginner.

Keep up the good work, and once again thanks for your contributions!
