- Fixes BUG#965, multiple responses in the same part (AND style)
now properly detect whether a situation is a previous submission or
not, previously it would detect a situation in which the same individual
response had appeared before (but not together) as a previously seen
submission, now it properly only detects when a group of submissions
is the same.
