Great!

However, this is only needed because we did not change `git.c` at the same
time (as I had done for `rebase` in 80dfc9242eb (git: mark cmd_rebase as
requiring a worktree, 2019-07-24)). In other words, I think we will also
want to address this part of `git.c`:

        /*
         * NEEDSWORK: Until the builtin stash is thoroughly robust and no
         * longer needs redirection to the stash shell script this is kept as
         * is, then should be changed to RUN_SETUP | NEED_WORK_TREE
         */
        { "stash", cmd_stash },

Other than that, I think your patch pair is good to go!

Ciao,
