irb のトップレベルで定義したメソッドの呼び出し制限が private ではなく public になってしまいます。

---

irb(main):001:0> def greeting
irb(main):002:1> 'hi'
irb(main):003:1> end
=> nil
irb(main):004:0> val = Object.new
=> #Object:0x007fe6ca05fd80
irb(main):005:0> val.greeting
=> "hi"
irb(main):006:0> val.private_methods.grep /greeting/
=> []
irb(main):007:0> val.public_methods.grep /greeting/
=> [:greeting]

public になるのは irb で実行したときのみです（ファイルに保存して ruby コマンドで実行した場合は private メソッドとして定義されます）。

I ran into this bug recently and I did a bit of investigating. This is due to a change introduced by #3406 (r29578) that made inner method definitions public regardless of the visibility of the method they were defined in.

I've attached a patch that calls private in the irb_binding method before returning the binding, which fixes the problem. I also verified that context mode 3 was the only mode affected by r29578 and that IRB works correctly when started via the command line and via IRB.start.
