[pstricks] Why don't \pscircle and \psellipse lift the pen before drawing their shapes?

[Counter Terrorist]

Dear folks,


I have tested all PSTricks closed curves (\psframe, \pscircle, \psellipse, \pspolygon and \pswedge) and I noticed that 
only \pscircle and \psellipse do not lift the pen (or liftpen=2) before drawing their shape.


Is it a feature by design or a bug?


Thank you in advance.


regards,
