A what?

This doesn't make any sense; rebase always operates on the current
branch, and Stefan wasn't asking for anything otherwise.  He was just
concerned that with --update-refs, one of the other branches it also
operated on was one he didn't want it to operate on.

Perhaps you meant
    git branch new
for your first command?

Leaving aside questions about how ref-stash is supposed to interact
with each and every other command out there, and how it's supposed to
know which branches it's operating on when you do pushes and pops...

Why do we need to invent a new command, when we already have the
reflog?  You could drop both ref-stash commands, and instead just have
a
   git branch -f new new@{1}
at the end (assuming of course "git branch new" was used instead of
your "git checkout -b new", as I suggested earlier) to put "new" back
to where it was before the rebase.  That's fewer commands.

Or, even simpler, drop the initial branch creation and both ref-stash
commands by just not creating the branch until after the rebase.
That'd make the entire set of commands just be:
   git rebase --update-refs [...]
   git branch new current_branch@{1}

Plus, either solution works today and needs no new changes.
