I guess I was too much into my stuff, and couldn't think straight on
how to search for this. Apologies, and thank you! :-)

Maybe I find https://public-inbox.org/git/20190927230747.yjdeaen34nnpcchy@camp.crustytoothpaste.net/
| grep -vP '^??' (or git-status-filtering equivalent; I'm in a rush to
commit this e-mail) somehow useful in my case

I tried to minimize the message, and left that important part out. I
am also part of the first case.

Then my fear/question remains:
* Wouldn't it be safer if it was "securely" stored in `refs/stash`
(i.e. `git stash push`) instead of `sha1="$(git stash create)"; echo
"Created autostash: ${sha1}"`?
  How is `rebase.autoStash = true` protected from "stuff" happening?
  A tin-foil hat example that I'm thinking is terminal output lost for
some reason and git rebase ancestor is killed -9.
  Or is there is "not much" to protect against?
* ... then `git stash` won't clean what it just stored. Is the
solution to also run `git reset --hard` here?
