将git远程名称重命名为“上游”

Question

I have a tiny problem with my git setup. I am working with forked repositories quite often. To fork them, I use the button on GitHub. After that, the command git remote -v shows me "origin" and "original-username".

"original-username" is now the upstream branch where I can pull changes from and create pull requests too. I would like to have this named "upstream" though. That would make it easier to use the same commands on different forks, and I can even create aliases with that.

So I know I can change the remote name with git remote rename original-username upstream , but that would mean I have to do it for every fork, every time I get that fork on a machine, and I have to make git remote -v first etc, and I am lazy :P
Also original-username is different on every fork.

So my question is:
Is there a possibility to rename the remote branch (from different names) to upstream, maybe with a cool alias function or a small script?

My dream woudl something like this:

[alias]
    setupstream = "!f(){ git remote rename $oldupstream upstream; };f"

$oldupstream should be gotten automatically, in some way.

Making the assumption that a local repository will only have two remote's configured where one is origin and the other is the one you want to rename something like this should work.

setupstream = "!f() { \
    local rem=$(git remote | grep -v '^origin$'); \
    if [ \"$(wc -l <<<\"$rem\")\" -gt 1 ]; then \
        echo 'Too many remotes.' >&2; \
        return; \
    fi; \
    if [ -z \"$rem\" ]; then \
        echo 'No non-origin remote found.' >&2; \
        return; \
    fi; \
    if [ \"$rem\" = upstream ]; then \
        echo '\"upstream\" remote already exists.'; \
        return; \
    fi; \
    git remote rename \"$rem\" upstream; \
    echo \"Renamed $rem to upstream.\"; \
}; f"
