I thiught about this, and I am not convinced that a single parameter is
enough to control the printing of containers.  For non-array containers
we need to limit the depth; for array containers we need to limit the
number of elements: I suppose that the current behaviour of not printing
contents of struct arrays that have more than one element is dictated by
this second need.

If the above is at least partially true, we need more than one
parameter.  For example, we could have struct_levels_to_print and
struct_array_elem_to_print.  By default, one could set them to print 3
levels, where arrays in the first 3 levels are printed only for the
first 10 elements.
