Try this:

$ git checkout v1.5.5
Note: moving to 'v1.5.5' which isn't a local branch
If you want to create a new branch from this checkout, you may do so
(now or later) by using -b with the checkout command again. Example:
  git checkout -b <new_branch_name>
HEAD is now at 1d2375d... GIT 1.5.5

[look around, and then ...]

$ git checkout HEAD~2
Previous HEAD position was 1d2375d... GIT 1.5.5
HEAD is now at f61cc48... git-svn: fix following renamed paths when tracking a single path

[go out for lunch ... and forget what this was about.]

$ git reflog -3
f61cc48 HEAD@{0}: checkout: moving from 1d2375d... to HEAD~2
1d2375d HEAD@{1}: checkout: moving from master to v1.5.5
c274db7 HEAD@{2}: pull : Fast forward

Here I have all the information to see what I did, and from what state.  
I even know that I did a pull on the master branch before moving away 
from it.  The -3 limits the log to 3 entries.  With no limit you get it 
all in your default pager.

So there is no need for another mechanism to find out what tag was 
actually checked out -- you have it all already.
