Log Message:
-----------
MatchData#string will return same class as original string. and will copy status of taint/untrust from original string.

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

class SubStr < String
  def value
    "value : " + self
  end
end

str = SubStr.new("hello\n world")
str.untrust
str.taint
s = str.match(/world/)
p s.string.value
assert_equal(SubStr, s.string.class)
assert_equal(true, s.string.tainted?)
assert_equal(true, s.string.untrusted?)

puts :ok
}}}
