Well, that might work now due to a bug in xkeyval 2.4
picking up presets for keys that are defined in another
family in the list than the one they are assigned to
(namely rjh). This will change in xkeyval 2.5 and make
you `solution' not work anymore. You can use the code
that I proposed.

The families in \pst at famlist, see xkeyval docs.
