Subject: [Rd] MASS: isoMDS drops names of points in R-2.1.0 (PR#7786)

isoMDS (MASS) drops names of points. The reason seems to be that R-2.1.0
abandoned names.dist that isoMDS uses to get the Labels attribute of dist
object:

    points <- matrix(tmp$y, , k)
    rn <- if (is.matrix(d))
        rownames(d)
    else names(d)   # This does not work any longer
    dimnames(points) <- list(rn, NULL)
    list(points = points, stress = tmp$val)

The solution is obvious but not very elegant.
