	While I am on postscript, this is a bug that I reported some time back
	on an earlier version that has not been corrected in 62.3:
	If line segments go to a point out of the clipping area of a plot and
	then back in, the lines are correct in the R window, but the line back
	in is missing in the postscript plot. Try saving the following as a PS
	file:
	plot(c(1,2,3),c(0,3,0),ylim=c(0,2),type"l")
	  Jim

This is now fixed in the latest development versions.  It wasn't just
a small patch -- I took the opportunity to boost efficiency of all line
clipping at the same time.
