changing git language

[berenger.morel@neutralite.org]

Hello.

I recently made an update, and git was one of the updated tools.
Now, I just tried it and, surprise, it is now speaking french... which 
I do not like. At all. I only use English when programming, for two 
reasons:
1: I am used to.
2: when you have a problem (and I often have things I do not know how 
to do with git), translating back the translation does not give very 
good results. Plus, it imply that I need to type what I wan't to search 
for, instead of copying the message from terminal.

So, does anyone knows how to change git's language, to help it forgot 
that it is on a French system?
