The special ref syntax :<n>:file refers to the blob in stage <n> of the
index. So you can see them with:

  git show :2:foo
  git show :3:foo

Or diff them with:

  git diff :2:foo :3:foo

You may also want to look at the git-mergetool script, which uses both
versions (along with the ancestor) as the arguments to many common merge
resolution programs.
