Note however that because you can generate new commits only on top of local branches (refs/heads/*), if you check out something other than local branch, e.g.:

  $ git checkout v1.7.8
  $ git checkout origin/next
  $ git checkout HEAD^

you would be after such checkout in unnamed anonymous branch which contents corresponds to what you checked out. This state is called 'detached HEAD', and shows e.g. in "git branch output as

  $ git branch
  * (no branch)
  master
  ...

On the other hand if you don't want to checkout tag to explore it, but set contents of working area to the state it was in given tag, you can use

  $ git checkout v1.7.8 -- .

HTH

P.S. Instead of Nabble you can use GMane interface, or just use email (you don't have ot be subscribed to git@vger.kernel.org to post, and it is custom here to send replies also to author(s)).
