I tried a short example, which seemed to work... snippet below.  The only
catch I found was I had to cast the number.  I think the operator
overload is sending the number into the character interpretor instead of
the numeric interpretor.

std::cout << setw(2) << (unsigned int)std::hex << buf[i];

that seemed to do the trick.  Shows the number as hex, space filling to
right align the output at two spaces.
