How would one go about disabling code formatting in Wakaba? Deleting this

	elsif(/^(?:    |\t)/) # code sections
	{
		my @code;
		while($lines[0]=~/^(?:    |\t)(.*)/) { push @code,$1; shift @lines; }
		$res.="".(join "<br />",@code)."";
	}

Doesn't seem to do anything but cause wakaba.pl to get stuck in and endless loop and consume 100% of my CPU.
