Another thing I also want to point out is that outside of this function... when git config is called with the --local, etc. the config scope is not actually CONFIG_SCOPE_LOCAL but CONFIG_SCOPE_UNKNOWN. This is because the config machinery pretty much equates --local and --file=./.git/config as pretty much equivalent (assuming ./.git is the actual repo directory location). So just something to keep in mind.
