Making it possible to do “git push origin” instead of “git push origin ”, without having to one-time prepare each branch for it

[Stefan Monov]

Hi.

I'd like to use just:

    git push

or at most:

    git push origin

rather than having to first check which is the active branch with `git
branch --list`, then type:

    git push origin <branch>

At [1] and [2] I've seen that if I do this once:

    git push -u origin <branch>

then from then on I can use just `git push` _for that branch_.
However, I don't want to do this "setup" step for each branch, because
it's extra work that I also may forget to do.

Why is this "setup" step necessary and can I avoid it?

Thanks,
Stefan
