* string.c (tr_setup_table): initialize negating table when
  negating string is given. [ruby-core:31851]

* string.c (tr_find): add a sentence for the time when
  target characters include negating one.

* string.c (tr_setup_table): fix bug in r29146.
  Initialize table even if cflag is 0; tr_find see whether
  del is empty or not.

* string.c (tr_find): nodel can't be NULL; if NULL, it means
  it is not specified.
