Re: [PATCH] show-ref: Allow --head to work with --verify

Junio C Hamano [off-list ref] writes:

If two codepaths are called "I don't see a meaningful difference",
then it is really better to share the same code.  Today, they may
happen to behave identically.  When we need to update the behaviour
of one, we'd be forced to update the other one to match.

IOW, something along this line, perhaps (not even compile tested so
take it with grain of salt).

By the way, I have no strong preference between "read-ref, check
quiet and show-one" and "show-ref", so if you make --verify to
consistently call "show_ref()" for both refs/heads/master and HEAD,
that is also perfectly fine.

I just do not want to see the same feature/codepath to call two
different implementations that happens to do the same thing today.

Thanks.
