Subject: * string.c (tr_trans): should squeeze properly.  [ruby-dev:34587]

* string.c (tr_trans): had a bug in treating multi-byte character
  replacement.

* string.c (rb_str_delete_bang): need not to do anything for empty
  strings.

* test/ruby/test_m17n_comb.rb (TestM17NComb::test_str_delete): add
  test for empty receiver.
