                     24: .B l
                     25: Print the byte number (decimal) and the
                     26: differing bytes (hexadecimal) for each difference.
                     27: .TP

                     35: If offsets are given,
                     36: comparison starts at the designated byte position
                     37: of the corresponding file.
                     38: Offsets that begin with
