It is intended and documented as such. From coreutils.info (9.3):

   "Without ‘--zero’, if FILE contains a backslash, newline, 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 
documented behavior.
