How to make IPython shell Ctrl-h working on Windows

Although I am a vim user. I like the shell emacs binding.
I can't live without it. I have been using IPython a lot
on Windows. IPython's pyreadline is marvalous. But it has
one shortcoming (defect?). That is the 'Ctrl-h' key doesn't
work like 'backward-delete-char'. I have been searching for
a solution, for a long time. Only when I found this post,
has the problem been sovled:

:) It is in Japanese. But who minds. Apply the patch to your
pyreadline's keysyms.py file. Ctrl-h is back!!

Post the patch below if the Japanese link scares you.
