R devel - Apr 2007 - Documentation update to R-lang.texi

Section 4.3.4 of R-lang.texi version 41191 in the paragraph that starts 
"When h(3) is..." explains that x and y are unbound variables in the 
function body of g in this example:

      f <- function(x) {
          y <- 10
          g <- function(x) x + y
          return(g)
      }
      h <- f()
      h(3)

while the paragraph following the example explains that "bound variables 
are those that match the formal arguments to the function." So wouldn't
x be bound?

I'll fix this in R-devel and the beta.
