I think we could get that behavior fairly easily by remembering the last
tag matching one of the commits on a branch, as we chase the branch
backwards. However, I'm not seeing a convenient way to extract the
commit SHA1s pointed to by the available tags. git tag doesn't tell
this and git show provides way too much information. Anybody know the
right incantation for that?
