A quick trial to recreate a tag object seems to succeed:

    $ git cat-file tag v0.99 |
    > sed -e '/-----BEGIN/,$d' |
    > git hash-object --stdin -w -t tag
    667d141b478eee5e53d2ee05acd61bb1f640249a
    $ git cat-file tag 667d141b47
    object a3eb250f996bf5e12376ec88622c4ccaabf20ea8
    type commit
    tag v0.99

    Test-release for wider distribution.

    I'll make the first public RPM's etc, thus the tag.

So we should be able to do something along the above line.  Here is
my quick-n-dirty one.
