Template Parser: Dont display var name if blank

[eluser]clip[/eluser]
I did this for a solution..

Code:

if($comments == FALSE)
{
     $data['comments'] = array(array('author'=>NULL,
                       'date'=>NULL,
                       'body'=>NULL
                                     )
                );
}
else
..... do more stuff

I haven't searched as to whether or not this is a known bug or not or is working as intended.
