Technically the last two snprintf's are unsafe, since the second argument
is a length, so we need to subtract the offset we supplied to the first
argument.
Also, there's no need to split the second snprintf from the third; both of
them can be combined to:
snprintf(n + idx, name_length - idx, "[%u]%s", length, array->name + idx);
Good catch on noticing that it's necessary to reverse the order of the
dimensions. With that fixed, this patch is:
