    Make :plus-integer actually print + or - as documented.
    
    The comment says the field should be proceeded with a + or -, but
    depended on negative integers producing the needed -.  When
    disassembling with a radix, this doesn't produce the expected output
    (#x7 vs #x-7 vs -#x7). So really print + or - followed by the absolute
    value.
