Agreed, but making that change does not make gtk_clist_moveto work correctly.
One of the problems is that the 'upper' value in the vertical adjustment in gtk_clist
is not updated as entries are added to the clist.

I attempted patching gtk_clist_moveto to call adjust_adjustments() before calculating
the adjustment value, but a later call to adjust_adjustments() in the gtk_clist undoes
my value.

I haven't worked my way through the logic of it all yet, so I haven't come up with a
decent patch.

I suspect that I might be able to put the widget into a state (like 'realized') that would
cause some of the state variables of the widget to be updated, so that adjustment
values would correctly reflect entries, but I do not understand the implications of this
well enough.
