[whatwg] colspan="0"

[Henri Sivonen]

None of Opera 9.02, Firefox 2.0, IE7 and Safari 2.0.4 implement  
colspan="0" as specified in HTML 4.01. Trident, Presto and WebKit at  
least agree on what to do with it: they treat it like colspan="1".

I suggest that only positive integers be conforming and that non- 
conforming values be treated as 1.
