select row bug in Fl_ListView

[nobody]

another bug in  Fl_ListView.  try to push  `tab+left`
for example in listview.
there was segmentation violation. i added one line to
fix it.

int Fl_ListView::handle_key()
{
    if(!children()) return 0;    
    Fl::event_clicks(0); // make program not think it
is a double-click    
    switch(Fl::event_key())
    {
/* ... */
    default: {
        int ret=0;
        ret = vscrollbar->send(FL_KEY);
        if(!ret) ret = hscrollbar->send(FL_KEY);
        
        if(ret)
        {
            if(Fl::event_key()==FL_Page_Up)
                select_only_row( row_at(yposition()) );
            else if(Fl::event_key()==FL_Page_Down)
            {
                select_only_row( row_at(yposition()+tih) );
            }
            if(cur_row > children())  cur_row = 0;
//<=========  segmentation  violation without it
            show_row(cur_row);
            return 1;
/* ... */
