Found mistake in SVG Primer

Under http://www.w3.org/Graphics/SVG/IG/resources/svgprimer.html#examples, in
the 'zigzag' example that looks like a 'W', the code is incorrect.

the 'd' attribute of 'path' reads

d="M 100 200 L 200 300, 300 20,0 400 300, 500 200"

but should be

d="M 100 200 L 200 300, 300 200, 400 300, 500 200"
