From the POSIX spec
(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.
I was staring at the same passage, but somehow it didn't "click" for me
that the above is _not_ saying that the NUL would terminate the string.

So I was worried too much and needlessly.  Thanks.
