From coreutils.info (9.3): "Without =E2=80=98--zero=E2=80=99, if FILE contains a backslash, newl= ine, or carriage return, the line is started with a backslash, and each problematic character in the file name is escaped with a backslash, making the output unambiguous even in the presence of arbitrary file names." You can argue that it ought to have been done differently, but it is the=20 documented behavior.
