Very interesting. I suspect it's because I did something funny, but I don't
know if what I did was actually wrong or if cgit is wrong here, or possibly
both.

This is what I did:

- I wrote the tag descriptions on my main build machine, as an annotated but
  not signed tag, since this machine does not have my gpg key on it,
  using git-2.1.0

- I uploaded the unsigned tags to the arm-soc git tree and downloaded them
  on the machine that does have my signing keys.

- For each tag I did 'git tag -fs $TAG $TAG' and signed the existing tag
  description with my gpg key, using git-1.8.1.2

- I uploaded the updated tags back to the public tree

>From looking at the tag now (e.g. git show arm64-for-linus), it seems
the third step ended up signing a tag that points to another tag instead
of a commit:

and both have the same text in them, which is not what I had expected.
