 140 The new data passed are in the "int nsel" and "int * selection"
 141
 142 The idea is to make a multiple selection from list of strings.
 143 The returned value is the total number selected. initialily there
 144 are nsel selected, with indices stored in
 145 selection[0],...,selection[nsel-1] which appear highlighted to
 146 begin with. On exit with value i
 147 selection[0..i-1] contains the indices of the selected items.
 148 (Some prior selectecions might be deselected.)
 149 Thus selection must be as big as choices, in case all items are
 150 selected.
