Changed paths:
  M io.c

Log Message:
-----------
revert my previous commit (d5d1e6f294dacf658b7c9fa4e3ae2effe7449315). because IO#read is broken after calling IO#ungetc.

Test Script:
{{{
require 'test/unit/assertions.rb'
include Test::Unit::Assertions

r, w = IO.pipe
w.write "foobar"
w.close

c = r.read(1)
r.ungetc(c)
assert_equal("foo", r.read(3))
assert_equal("bar", r.read(3))
r.close

puts :ok
}}}
