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.
