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