And make me responsible for tracking all post-publication changes in
R? (Now, what I should have had was regression tests in the ISwR
package failing when script output changed, but, well, "The road to
hell, etc...")

This particular change is very hard to find in NEWS, and even in the
SVN logs. It's a side effect of using format() inside print.table,
conspiring with R's default for string printing. This results in
getting right-justified strings (left-padded with spaces) printed
left-justified so that the names line up with the leading whitespace.
Try

  print(as.table(matrix(c(1,2,1,1e4),2)))

It actually was a paraphrased example, as those who can grep the TeX
sources found out...
