dupfinder.exe - exclude-by-comment

Hi,

I can't get dupfinder get to work with the exclude-by-comment parameter:

Let's say, I have a Class like:

/*
 * CodeInspection
*/
// CodeInspection

using System;
using log4net;

namespace.Common.Nationality
{
    /*
     * CodeInspection
     */
    // CodeInspection
    public static class NationalityManager {

// c# code with duplicates

}

I'm using this call:

dupfinder.exe duplocates.sln --o="out.xml" --discard-cost=70 --discard-literals --exlude-by-comment="CodeInspection"

But NationalityManager is still present in the findings. What am I doing wrong?
