 160 The new data passed are in the "int nsel" and "int * selection"
 161
 162 The idea is to make a multiple selection from list of strings.
 163 The returned value is the total number selected. initialily there
 164 are nsel selected, with indices stored in
 165 selection[0],...,selection[nsel-1] which appear highlighted to
 166 begin with. On exit with value i
 167 selection[0..i-1] contains the indices of the selected items.
 168 (Some prior selectecions might be deselected.)
 169 Thus selection must be as big as choices, in case all items are
 170 selected.
