I would say it's not entirely reasonable:

  - These are strings that users see frequently, and if they are not
    proficient in the English language I think it actually regresses
    their user experience.

  - The way this string is written would never lead me, as a script
    developer, to think that this is a message that should be parsed by
    my script. It's simply too user-focussed to make me think so.

  - Last but not least, I think it's not entirely unreasonable to ask
    script developers to use e.g. LANG=C when they expect strings to be
    stable.

Also, with the introduction of `git push --porcelain`, I think there is
even less reason to keep such user-visible strings intact. Any machine
that wants to parse output of git-push(1) should use `--porcelain`
instead in my opinion.
