 132
 133 The new data passed are in the "int nsel" and "int * selection"
 134
 135 The idea is to make a multiple selection from list of strings.
 136 The returned value is the total number selected. initialily there
 137 are nsel selected, with indices stored in
 138 selection[0],...,selection[nsel-1] which appear highlighted to
 139 begin with. On exit with value i
 140 selection[0..i-1] contains the indices of the selected items.
 141 (Some prior selectecions might be deselected.)
 142 Thus selection must be as big as choices, in case all items are
 143 selected.
