Yeah, we definitely shouldn't change this for alert or document.write

We have marked up some of the attributes and method parameters where  
the null value must be treated as "" instead of "null" with  
ConvertNullToNullString in our IDL. There are a number of method  
parameters that are not marked that way, but I'm not sure how many of  
these require the normal ECMAScript behavior and how many just haven't  
been changed.
