Auto-unfold for small number of items

[DirkReiners]

It would be great if we could set a limit for which arrays are automatically unfolded. We have a lot of results that can potentially have many items, but often only have one. Unfolding them by hand is a little tedious, so having a limit that tells the system to unfold if there are only less than n items would help a lot. This would work with show_to_level, so I would think it would make sense to unfold everything to the given level, if the number of items is less than the unfold_if_less_than value.

Thanks!
