I'm not particularly concerned about the master branch being
up-to-date, I'm more concerned about the repo's tags being up to date,
so perf --version will work correctly.

If you don't mind publishing all your local tags, and you don't want to
'push --tags' every time, adding this line to acme.korg's remote config
section will do it automatically:

push = +refs/tags/*

Thanks,
