Also... Delete all local tags on your system (then just run git fetch --tags to get them all again new, useful when the git repo is cleaned out)

function delete_all_local_tags {
git-for-each-ref --shell --format="%(refname)" refs/tags |
while read tag
do
tag_name=${tag/refs/tags//}
git tag ${tag_name//'/} -d
done
}
