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.
