  Log:
  Fix "slow (on-the-fly) zero fills percentage (`%slo-z')" some more.  The
  value printed is actually the optimized (i.e., the non-slow, not-on-the-fly
  zero fills percentage) except in overflow cases.  Describe it as %ozfod
  in the display.  Move the field descriptor 1 to the left so that there
  is space for 5 characters after the % sign (this leaves no space between
  the number and the descriptor but the % character serves well as a
  separator).
  
  Fixed integer overflow at z.ozfod = UINT_MAX/100 in the calculation of
  %ozfod.  This value can be reached just a few hours or minutes after
  booting, so %ozfod was usually garbage in boot mode.  Now %ozfod is
  correct in boot mode for a few days or hours.
  
  Print a non-dummy %ozfod when the division for it isn't division by 0
  instead of when the result will be less than 100%.  A result of 100%
  may be correct, though a result of more than 100% indicates overflow
  of one or both counters.
