The 'C' column is quite useful when tuning SMP systems, and something I
frequently look at when debugging performance issues in 5.x and 6.x.
Given that 'NICE' has a maximum width of three characters (-20 - 20), I
wonder if we can abbreviate that as 'NIC' or 'NCE' or such to reclaim one
character. On WCPU/CPU -- losing one of those should be fine.
