Ispcp v1.0.3 testers needed

[kazuo]

unless could lead to an endless loop and is unnecessary in this case.

An easy solution should be:

my ($data_length, $index_length) = (0, 0);

$data_length = @$_[6];
$index_length = @$_[8];

$size += $data_length + $index_length;

added in r2103

I reflect a revision and tested it, but the message is given. Why is it?
