That pulls in too many tags.  This is closer:

  git describe --tags --match "EMACS_2*" HEAD

which will break when emacs version 30 comes out, but it's good enough
for now.  For example, for the current origin/emacs-24 commit, that
comes out as:


which says we're 22895 commits past EMACS_23_4 in the repo, and the last
8 chars are "g" plus the head of the sha1 (6b5af2d), uniquely
identifying the commit.

If the head is precisely the tag, the output is just the tag, so for:

  git describe --tags --match "EMACS_2*" EMACS_23_4

we get


I think this has the properties you want, although the first part might
require massaging.
