The Blue Book allows the 'type' argument to be used in matpoints and
matlines.

	matlines(x, y, type="l", lty=1:5, pch=, col=1:4)

R-1.0.0 does not.

Thus, type="h", "b", must be invoked thru matplot( x, y, type = "h",
add=TRUE)

For the sake of consistency with S, it would be nice to have matlines
defined as:

"matlines" <-
  function(x, y, type = 'l', lty=1:5, lwd = 1, pch=NULL, col=1:6, ...)
  matplot(x=x, y=y, type=type, lty=lty, lwd=lwd, pch=pch, col=col,
          add=TRUE, ...)


and similarly for matpoints.
