Re: [PATCHv6 4/4] Write to $XDG_CONFIG_HOME/git/config file

> From: NGUYEN Huynh Khoi Nguyen <nguyenhu@ensibm.imag.fr>
>
> Git will be able to write to $XDG_CONFIG_HOME/git/config, a new
> configuration file following XDG specification, if:
> - this file already exists, and
> - $HOME/.gitconfig file doesn't, and
> - global option is used.
> Otherwise Git writes to $HOME/.gitconfig with global option, as usual.
> If you don't create $XDG_CONFIG_HOME/git/config, there is ABSOLUTELY
> NO change. Users can use this new file ONLY if they want.
> If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/config
> will be used.
> Advice for users who often come back to an old version of GIT:
> you shouldn't create this file.
