(http://pubs.opengroup.org/onlinepubs/9699919799/utilities/printf.html):

    In addition to the escape sequences shown in XBD File Format Notation (
    '\\' , '\a' , '\b' , '\f' , '\n' , '\r' , '\t' , '\v' ), "\ddd" , where
    ddd is a one, two, or three-digit octal number, shall be written as a
    byte with the numeric value specified by the octal number.

Looks pretty intentional to me.  \0 is a nul.
