upas/Mail: fix bug where Redraw must be executed twice to have an effect In showlist, call bwindata instead of bwinopen in order to use a pre-existing fd to write to the data file. This existing fd will properly honour any address set by a previous write to the addr file. Specifically, the redraw function sets addr to "," before calling showlist in order to overwrite the entire contents of the window.
