44 * The offset syntax of od(1) was genuinely bizarre. First, if
45 * it started with a plus it had to be an offset. Otherwise, if
46 * there were at least two arguments, a number or lower-case 'x'
47 * followed by a number makes it an offset. By default it was
48 * octal; if it started with 'x' or '0x' it was hex. If it ended
49 * in a '.', it was decimal. If a 'b' or 'B' was appended, it
50 * multiplied the number by 512 or 1024 byte units. There was
51 * no way to assign a block count to a hex offset.
53 * We assumes it's a file if the offset is bad.
