There was 2 persons who requested the patch off the list but I did not 
get any feedback from them.

Since I not sure we still use this joint in our simulator it might be 
better to wait.


By the way, I create simple unit test for my JointPR and JointPiston.

The unit testing facility used is UnitTest++ since CPPTestHarness seems 
to be orphan and the link to the page does not work anymore.

I will submit a patch for this next week if all goes well.
