The window put up by tcltk::tk_select.list appears to be of fixed width (20
chars), and is not wide enough to accomodate strings longer than 20 characters
long.  This can be easily fixed by setting the option "width = 0" in the calls
to tklistbox().  Width = 0 tells tk to make the listbox just wide enough to
accomodate the items contained in the list.
