* io.c (rb_io_each_byte): caused infinite loop. [ruby-dev:31652]

* io.c (rb_io_getc): should return nil at EOF, not EOFError.

* lib/delegate.rb (SimpleDelegator::__setobj__): use raise
  argument to specify backtrace.

* test/ruby/test_fnmatch.rb (TestFnmatch::bracket_test):
  String#include? no longer works for Fixnum.  use #chr.
