 169 The new data passed are in the "int nsel" and "int * selection"
 170
 171 The idea is to make a multiple selection from list of strings.
 172 The returned value is the total number selected. initialily there
 173 are nsel selected, with indices stored in
 174 selection[0],...,selection[nsel-1] which appear highlighted to
 175 begin with. On exit with value i
 176 selection[0..i-1] contains the indices of the selected items.
 177 (Some prior selectecions might be deselected.)
 178 Thus selection must be as big as choices, in case all items are
 179 selected.
