  New Revision: 16582

  Modified files:
    branches/ruby_1_8/ChangeLog
    branches/ruby_1_8/array.c
    branches/ruby_1_8/enumerator.c

  Log:
    * array.c (rb_ary_slice_bang): Be consistent with Array#slice()
      and String#slice!().  Just return nil when a negative length or
      out of boundary index is given instead of raising an exception
      via internal functions.
      (rb_ary_slice_bang): should not use rb_ary_subseq() which shares
      internal pointer.  splice modifies the receiver right after
      subseq.  [ruby-dev:34005]
      (rb_ary_slice_bang): should adjust length before making
      sub-array.
    
    * enumerator.c (Init_Enumerator): Override
      Enumerable::Enumerator#each_with_index with #with_index.
