I'm a through-and-through JJ convert. One papercut I have experienced a few times (though I am getting much better at avoiding) is what to do when I forget to `jj new`. Assuming that I have pushed the current bookmark to the remote, is there any way to recover a new change that is the diff against the remote? I have tried rebasing, but that leads to bookmark ambiguity instead of the solution I'm looking for.
