Crockford does express a preference when it comes to variable declarations

Hi Otto,

I was pleased to see this initiative and would like to contribute to it.

Crockford does express a preference when it comes to variable declarations.

Basically the same style as Idiomatic and jQuery prefer but with 4 spaces instead of 2.
```js
var foo = "",
    bar = "",
    quux;
```

##### On a other note
Crockford also prefers to give every variable line a comment but I don't know whether it is more appropriate to add this to the command or the variable declaration section
