[PATCH] Get rid of the last remnants of GIT_CONFIG_LOCAL

[Johannes Schindelin <Johannes.Schindelin@gmx.de>]

In dc871831(Only use GIT_CONFIG in "git config", not other programs),
GIT_CONFIG_LOCAL was rested in peace, in favor of not reading
/etc/gitconfig and $HOME/.gitconfig at all when GIT_CONFIG is set.
