   @suther You may remove whitespaces before calling difflib.SequenceMatcher - with this function you can remove trailing whitespaces:

   removeTrailingWhitespace = function(txt) {
       var pattern = /\s*$/g;
       var newtxt = [];
       for(var i=0;i<txt.length;i++) {
           newtxt.push(txt[i].replace(pattern, ''));
       }
       return newtxt;
   }
   
   var base = removeTrailingWhitespace( difflib.stringAsLines(basetxt) );
   var new = removeTrailingWhitespace( difflib.stringAsLines(newtxt) );
   
   var sm = new difflib.SequenceMatcher(base, new);
   (...)
