This one is not like the others. However, looking at the context I think
the pattern could just be (head tail id).

The only reason I can think of would be if these matches are sometimes
provided improper lists, which need to fail these match conditions. That
seems unlikely to me, but it should be clear from looking at the other
match clauses in each case.
