[pstricks] pst-node, ncangles

[E. Krishnan]

According to the available documentation on the pst-node package,
\ncangles should connect the ends of armA and armB by a right angle 
which meets armA also at right angles.  
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

But then I see that this right angle in fact meets armA at an angle 
(90 + 2angleA), so that the angle is indeed a right angle, when angleA is 
equal to one of the cardinal angles 0, 90, 180 or 270.
