Adding   to empty lines changes (and messes up) the actual source code

[dhm80]

In the class crayon_formatter.class.php you replace a blank line with a protected space:

// If line is blank, add a space so the div has the correct height
if ($code_line == '') {
    $code_line = ' ';
}

I guess (at this time) this is needed to display empty lines correctly but the problem is that you change the actual content. In some cases copying the source code with the extra added space ( ) messes up the copied source code.

So it would be great if you maybe added a CSS class instead of a space or something like that? Thanks a lot!
