Relaxed behavior: don't throw errors for impossible permutations,

but return an empty list.

* eval.c (perm_init_common): Do not throw error; return a nil
state if permutation length exceeds sequence length.
(perm_vec, perm_list, perm_str): Check for null return from
perm_init_common and return empty list.
(k_conses): Do not throw error; return empty list.
(comb_list_gen_fun): Check for nil value out of k_conses.
(comb): For vectors and strings, check length against k and
return nil if necessary. For lists, comb_list_gen_fun handles it.

* txr.1: Section order rearranged, and updated.
