Hi!
I'm native German, but German git messages confuse me (yopu'll have to correlate them with the man pages). At the moment git uses the locale settings from the environment, so you can only change git's locale settings by changing the environment (like "LANG= git ...").
OTOH Git has a flexible hierachical option setting mechanism. Why not allow a Git language (locale) setting system-wde, user-wide, or repository-specific.
