Hi Zhida,

I guess you are not familiar with git, because you removed the
commit log in this version.
Other strange thing, there is no uppercase in your name in the
From field, which will be converted in author name. French people
cares about uppercases in names ;)
Last thing: new versions should be sent with --in-reply-to option:
