[whatwg] Default value of "complete" attribute on new Image objects

[Diego Perini]

Just to add that also by using DOM methods like:

   document.createElement('img').complete; // true

the result is the same: "complete" is always true. Only tested on Firefox
3.5.10 and Opera 10.60.

On FF after setting src="" the "complete" property return true while on
Opera it return false.
On FF after setting src="/nonexisting.gif" the "complete" property remains
true like it does in Opera.

Ugh ! Quite an unreliable behaviour... I would expect false in all the above
cases.
