Correct the example introduced in rev 1.29, which suggested a block:frag
size ratio other than 8:1. Currently, we only recommend an 8:1
ratio, because the impact of others ratios has not been adequately
investigated.
Also, do not recommend the use of the -c option in the example, since
newfs now automatically calculates the best cyl:cylgrp ratio.
This change was discussed with the author of rev 1.29.
