Actually the same thing happens with any repeated _Group subclass
(e.g. Radiogroup). A patch is below for _Group->prepare_attrs, based
on some similar code in _Field->_render_value. Note that it still
handles the case of a single multi-Select (i.e. with the "multiple"
attribute) or Checkboxgroup, by checking whether there are multiple
fields with the same name and leaving the value array alone otherwise.
It's possible that some forms could be relying on the current
behavior with multiple multi-Selects with the same name that have
disjoint option lists, but this seems unlikely?
