[pstricks] lineAngle

[Michael Sharpe]

I'm seeing some problems with the new lineAngle keyword in \ncdiag and  
relatives. (Using pstricks-add 3.08, dated 2008/08/06, but same  
behavior in prior versions.)

1. Setting lineAngle=0 does not give a connector with slope 0, though  
one may obtain essentially slope 0 by setting lineAngle=.001.

2. Setting lineAngle=0 changes armB slightly from the value it takes  
when lineAngle is not given a value.

Example

\usepackage{pstricks,pst-node}
\usepackage{pstricks-add}
\begin{pspicture}(6,6)
\rput(2,1){\ovalnode{A}{node A}}
\rput(5,5.5){\dianode{B}{node B}}
\ncdiag[angleB=-90,lineAngle=0]{A}{B}
\end{pspicture}
