That's not what the manual says for -b -- it is what it says for -B.

     -B      Force printing of non-printable characters in file names as \xxx,
             where xxx is the numeric value of the character in octal.

     -b      As -B, but use C escape codes whenever possible.

So -b uses "escape codes" and not "octal escapes".

POSIX/SuS does not define the behavior of -B and -b, so I think we can
go for what is "most reasonable".
