This means that the '*' and the different color are coded in C, hence
it's not possible to mimick this using "git for-each-ref --format ...".
I do not consider this as blocking, but I think the ultimate goal should
be to allow this, so that all the goodies of "git branch" can be made
available to other ref-listing commands.

I actually prefered the old way: current is a Boolean that says
semantically "this is the current branch", and the Boolean is turned
into presentation directives in a separate piece of code.
I'd write
char c;
int current = 0;
...
if (...)
current = 1;
...
case REF_DETACHED_HEAD:
current = 1;
...
and keep the last hunk.
(IOW, turn current from a parameter into a local variable)
