Yeah, you're supposed to use the existing code, but I guess your
approach works too.

I think git request-pull just uses "git cat-file" instead to show the
tag contents, but yes, I guess you can use "git tag -l --format" too.

This is what git-request-pull does:

        git cat-file tag "$head" |
        sed -n -e '1,/^$/d' -e '/^-----BEGIN PGP /q' -e p

but admittedly "get cat-file" is a really low-level plumbing thing.
It's basically how you get the raw data out of any git object.
