I wondered if we should explain the significance of "last" a bit
more (like "this results in the value from the most specific
configuration file to be used, the ones in $GIT_DIR/config
overriding what is in $HOME/.gitconfig"), but I do not have a strong
opinion either way.  Let's queue this for 'maint' for now.
