Re: [PATCHv7 1/4] Read (but not write) from $XDG_CONFIG_HOME/git/config file

> Git will be able to read from $XDG_CONFIG_HOME/git/config, a new
> configuration file following XDG specification. In the order of
> reading, this file is between global configuration file and system
> wide configuration file. Git currently does not write to this new
> configuration file. If $XDG_CONFIG_HOME is either not set or empty,
> $HOME/.config/git/config will be used.
