Fallback to AppData if XDG_CONFIG_HOME is unset

Browse Source 
In order to be a better Windows citizenship, Git should
save its configuration files on AppData folder. This can
enables git configuration files be replicated between machines
using the same Microsoft account logon which would reduce the
friction of setting up Git on new systems. Therefore, if
%APPDATA%\Git\config exists, we use it; otherwise
$HOME/.config/git/config is used.
