Coverity complained about this code, apparently because it uses a local array of size FUNC_MAX_ARGS without a guard that the input argument list is no longer than that. (Not sure why it complained today, since this code's been the same for a long time; possibly it re-analyzed everything the List API change touched?) Rather than add a guard, though, let's just get rid of the local array altogether. It was only there to avoid list_nth() calls, and those are no longer expensive.
