That is in general impossible.
$ git show-branch master~1 next pu
! [master~1] blame: Nicer output
! [next] Merge branch 'jc/cvsimport' into next
! [pu] Merge branch 'jc/cvsimport' into next
---
-- [next] Merge branch 'jc/cvsimport' into next
++ [next^2] cvsimport: honor -i and non -i upon subsequent
imports
-- [next^] Merge branch 'jc/fetch' into next
++ [next^^2] fetch: exit non-zero when fast-forward check
fails.
-- [next~2] Merge branch 'ew/abbrev' into next
++ [next~2^2] ls-files: add --abbrev[=<n>] option
++ [next~2^2^] ls-tree: add --abbrev[=<n>] option

+++ [master~1] blame: Nicer output
$ git rev-parse --verify master~1
88a8b7955666ed8fa5924fadbb3bb58984eaa6af
Now what should this command say?
$ git branch --tell 88a8b7955666ed8fa5924fadbb3bb58984eaa6af
It is not head of any branch. Should it say master~1?
next^2~1? pu^2~1?
The closest thing is name-rev, which tries to give you the
simplest. It may or may not match what you want:
$ git name-rev 88a8b7955666ed8fa5924fadbb3bb58984eaa6af
88a8b7955666ed8fa5924fadbb3bb58984eaa6af master~1
$ git name-rev `git rev-parse --verify b14e24`
b14e2494b8a70737066f4ade4df1b5559e81b44b todo~16

... I wonder why you care. Wouldn't this work just as well?
$ git rev-list --header --topo-order --parents --remove-empty \
--all -- <path>
It lists 70 commits at the moment.
