Forget about my first answer.

git-describe shows the most recent tag that is reachable from a commit, but
80786722b116f5002c28e9e0200044f825b236f6 isn't reachable when your HEAD is
at 8482c7b836a66f874e7dfea9c35fee4a82ad817b.

As git says, there's only an unannotated tag:

$ git describe 
fatal: No annotated tags can describe '8482c7b836a66f874e7dfea9c35fee4a82ad817b'.
However, there were unannotated tags: try --tags.

$ git describe --tags 
man-pages-2.25-30-g8482c7b
