"git describe --debug" does not show the latest tag for "groff"

What did you do before the bug happened? (Steps to reproduce your issue)

  I do not know, it could have happened anytime after the latest tag
was committed (11th Nov. 2020).

What did you expect to happen? (Expected behavior)

  Seeing the latest tag "1.23.0.rc1" in the version string of "groff"
(and in the output of "git describe --debug")

What happened instead? (Actual behavior)

  "groff --version" shows for example "1.22.4.3317-8f8c8-dirty"

  "git describe --debug" shows:

What's different between what you expected and what actually happened?

  The latest tag is not shown for the groff version.

Anything else you want to add:

  The latest tag in "git log" is 1.23.0.rc1 in my branch.
  It is 1.23.0.rc1 in branch master.

  Search for "tag:" in "git log" in my branch shows:

commit c05b538c504106d55b81caa6400ea80797f03775 (tag: 1.23.0.rc1)
Author: Bertrand Garrigues <...>
Date:   Wed Nov 11 01:58:55 2020 +0100

  "git show-ref 1.23.0.rc1" in my branch shows:

faa3dff8d011e61721e763c71b6ccbf20a4675bc refs/tags/1.23.0.rc1

####

  "git-version-gen" (gnulib) does not get the latest tag.

  The call in configure.am is:

AC_INIT([GNU Troff],[m4_esyscmd(build-aux/git-version-gen --prefix "" .tarball-version)],[http://savannah.gnu.org/bugs/?group=g$

  The files ".git/packed-refs" and ".git/info/refs" are the same in both
branches.
