Comment 1 for bug 874290

In the 10 whitespaces els if statement, there should be a check for $k2. If it doesn't exist, an undefined variable error is returned:

if ($k2) {
    if($hdr) {
        $pro->{$typ}->{$hdr}->{$k2}->{$k3} = $v3;
     } else {
        $pro->{$typ}->{$k2}->{$k3} = $v3;
     }
} else {
    if ($hdr) {
         $pro->{$typ}->{$hdr}->{$k3} = $v3;
    } else {
       $pro->{$typ}->{$k3} = $v3;
    }
}

I have also modified the code in order to enable automatic calculation of the whitespaces, instead of declaring by hand the four cases (4, 6, 8, 10 whitespaces).
