Backport #1151: Aliased methods change super logic when retrieved with 
Object#method

 This is a peculiar case I don't believe I've reported before. It seems 
that "method" can change the super behavior of an alias:

  # Test weird likely-a-bug where method() will repurpose where super 
goes to
  class Foo222
    def a; 'a'; end
    def b; 'b'; end
  end

  class Bar222 < Foo222
    def a; super; end
    alias b a
  end

  puts('a' == Bar222.new.b) # true
  puts('a' == Bar222.new.method(:b).call) # false

 Ruby 1.9 behaves as you would expect, calling the "a" super method in 
both cases. We changed our behavior in JRuby 1.1.2 to match Ruby 1.8.6, 
but I still believe this is a bug. The JRuby bug report is here: 
http://jira.codehaus.org/browse/JRUBY-1192 and I reported it to 
ruby-core here: 
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/... and a 
patch was proposed here: 
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/.... Since 
it behaves as I expect in 1.9, I assume the 1.8.x behavior is incorrect.
