Answer 1

If you are not sharing your repo with others, this is useful to push all your branches to the remote, and --set-upstream tracking correctly for you:

git push --all -u

(Not exactly what the OP was asking for, but this one-liner is pretty popular)

If you are sharing your repo with others this isn't really good form as you will clog up the repo with all your dodgy experimental branches.
