I'm not sure. I do support "upstream", but I also think that in many
(most?) cases, the user will want to set "upstream" to point to the
branch with the same name. If there is any confusion between "current"
and "upstream", then avoiding situations where they do something
different is not stupid. This is already what we do when there is no
upstream configured at all:

  $ git push origin
  fatal: The current branch master has no upstream branch.
  To push the current branch and set the remote as upstream, use
  
      git push --set-upstream origin master

OTOH, if the user sees this message, he already has several remotes
configured, and we can probably expect him not to be a total newbie.
Then suggesting

  "git push --set-upstream %s %s:<remote-branch-name>", remote->name, branch->name

would make sense.
