I think this has always been the issue with trailing control characters (or at least certain ones) that don't amount to anything in the copied line. It has to do with Khaled's truncated line copy code, which does its best to reformat control characters from partial copies so that they still make sense and WYSIWYG. I'm not sure if Khaled can detect when a full line is selected so that it can forego this format kungfu and smack the raw text into the clipboard. Maybe this just needs a new key combo like Ctrl+Shift + Select.
