Push to upstream by default

Just set your push.default to upstream to push branches to their upstreams (which is the same that pull will pull from […]), rather than pushing branches to ones matching in name (which is the default setting for push.default — matching).

—Brian Campbell on Stack Overflow

[push]
    default = upstream

Useful for easily pushing to a remote branch with a name different from that of the local branch. Long-form method:

git push origin local-branch:remote-branch
