Formatting of empty array produces a PHP syntax error.

When running the coder formatter on an exported CCK type the result produces PHP that fails a syntax check using php -l filename

An exported CCK text field may very often contain this:

    'default_value' => 
    array (
    ),

after processing with the code_formatter.php it now looks like this:

    'default_value' => 
    array (,
    ),
