R devel - Sep 2001 - Bizarre clipping with abline and points (PR#1095)

I want to put some points along the horizontal axis.
> plot(1:10, 1:10)
> points(4, par("usr")[3], xpd=TRUE)
> abline(v=5)
works fine for me.  But if I try
> plot(1:10, 1:10)
> abline(v=5)
> points(4, par("usr")[3], xpd=TRUE)
then the points are clipped.  The call to abline seems to be
enforcing xpd=FALSE for later calls to the plot.

Cheers, Jonathan.

Confirmed, same effect with 

plot(1:10, 1:10)
points(4, par("usr")[3], xpd=FALSE)
points(4, par("usr")[3], xpd=TRUE)
