The func PutN in class TSuperTableString is wrong

[GoogleCodeExporter]

Hi, it is really hard to visit Google in China now.

First of all, thanks for everyone who worked on superobject, it is an awesome 
unit for parsing json text.

I read the code and found that may be it is wrong code in func PutN of 
TSuperTableString.

Here is the code on line 5826:

procedure TSuperTableString.PutN(const k: SOString; const value: ISuperObject);
begin
  if value <> nil then
    PutO(k, TSuperObject.Create(stNull)) else
    PutO(k, value);
end;

And I thought it would be right like this:

procedure TSuperTableString.PutN(const k: SOString; const value: ISuperObject);
begin
  if value <> nil then
    PutO(k, value) else
    PutO(k, TSuperObject.Create(stNull));
end;

Regards
