Right. The pattern (to the degree that there is one) would have you
creating a function named something like svn_client__list_internal(), which
has all the code from svn_client_list3() plus the extra (optional)
parameters and functionality you need. svn_client_list3() then becomes a
thin wrapper around that function.
