130 *
131
132 The new data passed are in the "int nsel" and "int * selection"
133
134 The idea is to make a multiple selection from list of strings.
135 The returned value is the total number selected. initialily there
136 are nsel selected, with indices stored in
137 selection[0],...,selection[nsel-1] which appear highlighted to
138 begin with. On exit with value i
139 selection[0..i-1] contains the indices of the selected items.
140 (Some prior selectecions might be deselected.)
141 Thus selection must be as big as choices, in case all items are
142 selected.
