[pstricks] Another node connection needed

[Boris Veytsman]

Greetings,

I think I need another type of node connection.  It is like ncbar (or
ncbarr in pstricks-add), but has 5 segments.

1.  Two segments armA and armB go from nodes A and B with angles
    angleA and angleB correspondingly.

2.  The ends are connected by \ncbar with arm armC and angle angleC.

Here is an example with angleA=0, angleB=-180, angleC=90:

     -----------
     |         |
  A---         -----B

Many thanks!

Good luck

-Boris
