POSIX allows double slashes having an implementation-defined meaning. See SUSv3, chapter 4.11 Pathname Resolution: http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap04.html#tag_04_11 especially the last paragraph. So NCDU is behaving non-portable in this case (as a lot of other applications, too, unfortunately).
