Could you sanity check this before I knock myself out, deleting old branches?

script and adds the branch ignore/foo as
swap "deletes" and "adds" part, because a) emotionally better, b) actually the
order in which scripts works.

Executing the following in a v8 workdir checkout to archive in batches of 10
(excluding current milestone 5.4.*):

git branch -a | grep -E "^  remotes/origin/(.+\..+\..+)$" | grep -vE "^ 
remotes/origin/(5\.4\..+)$" | cut -d / -f 3 | xargs echo | xargs -n10
/usr/local/google/home/machenbach/v8/infra_experimental/machenbach/archive/archive_branches.py
.

Meh - this didn't delete the pending ref and pending tag branches :/
Will have to delete those manually...

[Michael Achenbach, 2016-08-09 09:17:29]

Deleted the other refs with:

ls -l .git/refs/pending/heads | cut -d " " -f 10 | grep -E "^.+\..+\..+$" | grep
-vE "^5\.4\..+$" | awk '{print ":refs/pending/heads/"$1}' | xargs -n10 git push
origin

ls -l .git/refs/pending-tags/heads | cut -d " " -f 10 | grep -E "^.+\..+\..+$" |
grep -vE "^5\.4\..+$" | awk '{print ":refs/pending-tags/heads/"$1}' | xargs -n30
git push origin
