Do you have multiple (annotated) tags for the same commit? Otherwise, I
don't see why "git describe HEAD" should print the wrong one. If there's
a tag that can be resolved to the same commit that HEAD can be resolved,
then "git describe HEAD" must output that one. Otherwise, that'd be a
clear bug to me.
