'git branch' shows which branch you are currently on with an '*', but 'git for-each-ref' misses this feature. So, extend the format with %(HEAD) to do exactly the same thing. Now you can use the following format in for-each-ref: %C(red)%(HEAD)%C(reset) %C(green)%(refname:short)%C(reset) to display a red asterisk next to the current ref.
