Most of the similar code uses scm_c_memq instead, which skips the
checking.   On closer inspection,  scm_ilength (which does the actual
checking) also catches other errors besides circular lists.

We could make more strict checking a habit, but it's not really a
scalable, since many routines require more complex data structures as
input parameters.
