/* Multiple choice dialog contributed by Robert Cowell
 *

The new data passed are in the "int nsel" and "int * selection"

The idea is to make a multiple selection from list of strings.
The returned value is the total number selected. initialily there
are nsel selected, with indices stored in
selection[0],...,selection[nsel-1] which appear highlighted to
begin with. On exit with value i
selection[0..i-1] contains the indices of the selected items.
(Some prior selectecions might be deselected.)
Thus selection must be as big as choices, in case all items are
selected.
