Gitk provides both. What I want is listed on the "Preceeds" line in
the lower right hand box (the sixth line from the top in the

Yeah, I'm not talking about the tag and branch names that show up in
the top gitk box (and which you can also get via git log --annotate).
I'm specifically talking about what you get with:
