 138 The new data passed are in the "int nsel" and "int * selection"
 139
 140 The idea is to make a multiple selection from list of strings.
 141 The returned value is the total number selected. initialily there
 142 are nsel selected, with indices stored in
 143 selection[0],...,selection[nsel-1] which appear highlighted to
 144 begin with. On exit with value i
 145 selection[0..i-1] contains the indices of the selected items.
 146 (Some prior selectecions might be deselected.)
 147 Thus selection must be as big as choices, in case all items are
 148 selected.
