snd_use_case_get_list returns lists of strings that are either: a) A sequence of single strings b) A sequence of pairs of strings all flattened into a single list
The current list command assumes layout (b) above, and hence prints nothing when printing a single-entry list that's actually in layout (a). Add a new command "list1" to dump lists in layout (a).
