I didn't get back the latest tag by 'git describe --tags --always' if I have two tags on the same commit.

// repository ppa:git-core/ppa

(master)⚡ % cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=16.04 DISTRIB_CODENAME=xenial DISTRIB_DESCRIPTION="Ubuntu 16.04.2 LTS"

(master)⚡ % git --version git version 2.11.0

(master) [1] % git show-ref --tag 76c634390... refs/tags/1.0.0 b77c7cd17... refs/tags/1.1.0 b77c7cd17... refs/tags/1.2.0

(master) % git describe --tags --always 1.1.0-1-ge9e9ced

### Expected: 1.2.0

* "git describe" did not tie-break tags that point at the same commit
  correctly; newer ones are preferred by paying attention to the
  tagger date now.
