I could have a couple of local branches typically pushed to a couple of
remote branches. "git push origin" would update all remote refs.

But I may also be interested to push only the current branch I'm working
on. I may also have some pending fixes on another branch that should not
be pushed now. Currently I need to do "git push origin  
<current>:<someremote>".

Let me put it as a question: How can I push changes from the current
branch to all remote refs it is configured to push to via  
"remote.<name>.push"
without pushing anything else at the same time?
