the directory, we use --exclude path/dir_1 --exclude path/dir_2 --exclude path/dir_3
everything works correctly but when we want to exclude file - PhpCpd.php
sends command like --names-exclude path/file_1 --names-exclude path/file_2
--names-exlcude path/file_3 and files will be scanned for copy/past, to ignore all three file we have to use
command like --names-exclude file_1,file_2,file_3 without paths.
