We have a lot of these little differences. No reason to waste time on
them, unless we get actual complaints, I'd say.

(Here's a couple of additions to the list of differences:
 
   aovtable <- anova(KW.lm)$table
    Statistic <- aovtable["group","Sum Sq"]

    s <- summary(KW.lm)
    Statistic <- s$coefficients["group","t Value"] *
      s$sigma 

[anova returns a table, rather than a list containing a table, in S and
uses "Sum of Sq" and "t value"])
