[PATCH 2/3] for-each-ref: introduce %(HEAD) asterisk marker
'git branch' shows which branch you are currently on with an '*', but
'git for-each-ref' misses this feature. So, extend its format with
%(HEAD) for the same effect.
Now you can use the following format in for-each-ref:
%C(red)%(HEAD)%C(reset) %(refname:short)
to display a red asterisk next to the current ref.
