  Scratch my previous answer, I was confused with too many digits (868
vs 870). In fact looking at the code, if there is an annotated tag in
the ancestry, git describe will always prefer it to lightweight tags.

  the problem with lightweight tags is that they are meant to be moved,
hence are not really something you want to base on to chose a uuid
(which git-describe generates).
