You could just create a static function with those extra arguments and make
the outer svn_client_list3() call into that function.
Please try to avoid adding implementation details to the public api, unless
absolutely necessary.
(We have such wrappers in almost every case where we use externals)

This model would also allow future improvements like re-using the
ra-session, without updating the public function prototype.
