make check and postscript output in R 1.7.1

It's telling us that your machine gives different output from *all* the 
other machines that were checked in the beta-test period.   So what 
machine is this that no one beta tested?   (In future please do 
participate in the beta test so your unusual system gets tested.)

As Rob G has reported this from FreeBSD earlier today it is probably 
already fixed in R-devel (it is for him).  Fortunately the difference is 
in this case negligible.

I think this might be telling us that reg-plot.ps.save needs to be 
updated for the new version of postscript().
