#289 Output statistic descriptions in help

[Paul Demorest]

I've noticed that the list of profile statistics output (for example) via zap tfzap stat=help no longer includes the description string for each statistic as it used to a while back. Since these options are pretty cryptic it would be good to restore the descriptions (unless there is another way to access this info?).

This has also been bother me ... thank for the nudge. I've checked in a fix (cfb3ce2da..0444b1f5f).
