[pstricks] pstricks-add:hookarrow

While with hookright(left)arrow it is possible to change the side of the hook:

\psline[hookwidth=3mm]{-H}(0,0)(2,0)
% hook on left side

\psline[hookwidth=-3mm]{-H}(0,0)(2,0)
% hook on right side

this seems not to be possible with hookarrow

\psline[hookwidth=-3mm]{-h}(0,0)(2,0)
% no effect, alwalys on right side

Looking at the code, there is no hookwidth defined for arrow type h.
Is there a way to change the side of the hook? I need it for typesetting the 
equilibrium arrows in chemical formulas.

Regards

Bernd
