    mem: Only print counter totals if >0
    
    At the end of each successful test run we print out a useless list of
    all zeroes. We don't need to print out the counter totals unless they
    are nonzero; in the case where they are all zero we already print out
    "0 objects currently alive".
    
    We also increase the number of spaces printed out, since
    object_prototype already overflows the allotted 12 spaces.
