No, the awkwardness is that we set the pointer once in
property_copy_string_array(), then fetch it in
property_entry_copy_data() only to set it again via
property_set_pointer(). This is confising and awkward and I believe it
is cleaner for property_copy_string_array() to give a pointer to a copy
of a string array, and then property_entry_copy_data() use it when
handling the destination structure.

Thanks.
