encoding.c: revert r41964

Browse Source 
* encoding.c (enc_set_index): since r41967, old terminator is dealt
  with in str_fill_term().  should not consider it here because this
  function is called before any encoding is set.

* encoding.c (enc_inspect): use PRIsVALUE to preserve the result
encoding.
* encoding.c (enc_set_index): deal with terminator so that
rb_enc_set_index also works.
