[pstricks] npos problem

[Michael Sharpe]

According to TLGC2, npos=3 should be permitted within an \ncangle, but  
I get a Postscript error when I try to convert the resulting .ps to  
a .pdf. (With \ncline, npos=1 is OK,  but with all other connections  
having more than one segment, the highest value for npos fails in the  
same way.) Backing off by epsilon works OK in all cases. Since npos=0  
is always OK, it seems like there's an asymmetry here that might be  
fixable.
