|    config: read (but not write) from $XDG_CONFIG_HOME/git/config file
|
|    Teach git to read the "gitconfig" information from a new location,
|    $XDG_CONFIG_HOME/git/config; this allows the user to avoid
|    cluttering $HOME with many per-application configuration files.
|
|    In the order of reading, this file comes between the global
|    configuration file (typically $HOME/.gitconfig) and the system wide
|    configuration file (typically /etc/gitconfig).


However git/config.c (git_config_early) commit accesses xdg_config
before user_config.  So the comments and documentation are
inconsistent with the code.

[This looks like an intentional bug, I spotted it when commenting out
 the accesses to files under ~/.config.  (protip: chmod 000 ~/.config helps
 identify and blacklist NWO "apps" and now git started complaining) ---Madhu
