Subject: [PATCH 0/3] a small branch API clean-up

From: Junio C Hamano <[email-masked]>
Date: Fri, 13 Oct 2017 14:11:29 +0900

This started as a little clean-up for a NEEDSWORK comment in
branch.h, but it ended up adding a rather useful safety feature.

Junio C Hamano (3):
  branch: streamline "attr_only" handling in validate_new_branchname()
  branch: split validate_new_branchname() into two
  branch: forbid refs/heads/HEAD
