The ref transaction can fail after the user has written their tag message. In
particular, if there exists a tag `foo/bar` and `git tag -a foo` is said then
the command will only fail once it tries to write `refs/tags/foo`, which is
after one has closed the editor.

Hold on to the message file for a little longer so that it is not unlinked
before the fatal error occurs.

As I said in my review of [1/3], TAG_EDITMSG should be documented
just like COMMIT_EDITMSG is documented.

Other than that, looking OK to me (I didn't read the patch very
carefully so I may have missed leaking and/or use after free,
though).

Thanks for working on this.
