Hi,

This puzzled me a lot, so I try various configuration:
- I was able to create an annotated tag on an annotated tag (this can 
be recursively)

   git tag -a -m "tagged a tag" test_tag_tag v1.8.2
   git show test_tag_tag

- I was able to tag a file

   git tag -a -m "tagged a file" test_tag_file `git ls-tree HEAD | awk 
'{ print $3; exit; }'`
   git show test_tag_file
   git show -p test_tag_file

Is there any other kind of object that can be tagged ... and what is the purpose of this ?

Regards.
