Or, just use name-rev so it works with non-linear histories too:

git log | git name-rev --refs=$(git symbolic-ref HEAD) --stdin | less

That'll add things like "master~7" for stuff in the first parent
history and output like "master~7^2~3" for commits on side-branches,
either of which can be fed to other git commands.
