    Fix build failure reported in gcc 9.
    
    Apparently gcc 9 is clever enough to say 'Hey, runtime field width in
    an sprintf targeting a fixed-size buffer!', but not clever enough to
    notice that the width was computed earlier as the max of lots of
    default-width sprintfs into the same buffer (so _either_ it's safe, or
    else - on a hypothetical platform with a 263-bit int - the damage was
    already done).
    
    Added a bounds check or two to keep it happy.
