Nobody replied to this, so maybe there's no terse
way to do this -- if there is, I'd still like to hear it.

If there isn't, though, and in case anybody's curious, here's
what I decided to do: I connect to the size_allocate signal, and
then execute the following:

#define CLIST_NROWS_VISIBLE 4

static gint
clist_size_alloc_cb (GtkWidget *w, GdkEvent *event, ggobid *gg)
{
  if (!widget_initialized (w)) {
    gint fheight;
    gint lbearing, rbearing, width, ascent, descent;
    GtkStyle *style;
    GtkCList *clist = GTK_CLIST (w);
    style = gtk_widget_get_style (w);
    gdk_text_extents (style->font,
      "arbitrary string", strlen ("arbitrary string"),
      &lbearing, &rbearing, &width, &ascent, &descent);
    fheight = ascent + descent;

    gtk_widget_set_usize (w, -1,
      CLIST_NROWS_VISIBLE * fheight +
      (CLIST_NROWS_VISIBLE-1) * 1 +  /*-- 1 = CELL_SPACING --*/
      clist->column_title_area.height);

    widget_initialize (w, true);
  }

  return true;
}

widget_initialize() and widget_initialized() are utilities that
protect me from the fact that gtk_widget_set_usize triggers yet
another size_allocate event.
