[css3-values] incorrect font-family syntax in example

CSS3 Values and Units includes this property value example:

  ‘font-family’  <family-name>#  ‘"Gill Sans", Futura, sans-serif’

This isn't correct relative to either CSS 2.1 or CSS3 Fonts,
because the syntax in the value definition field is more
complicated than simply <family-name>#.  I think the simplest
thing to do would be to remove this example, since font family
lists are a tender, special beast and we should probably avoid
confusing anyone about this.
