It can be more complex than you realize.

   $ git pull --rebase --stash

    It seems that there is already a .git/rebase-apply directory, and
    I wonder if you are in the middle of another rebase.  If that is the
    case, please try
            git rebase (--continue | --abort | --skip)
    If that is not the case, please
            rm -fr .git/rebase-apply
    and run me again.  I am stopping in case you still have something
    valuable there.

If I follow the latter advice about 'rm -rf', who will remember that
'rebase' had something stashed, and what will they do with it when
they do?

What if it is weeks or months later?  I would be surprised to see
long-forgotten wip show up in my workspace all of a sudden.
