Actually, it is not Junio's Meta that needs checked out, but rather the
"meta" branch where you will find that "rebase" script. If other people
find them useful, the set of scripts could perhaps be transitioned to a
namespace that is appropriate to go into people's $PATH.

I didn't really expect anybody to use it verbatim, though. I was
providing it more for inspiration.

Yes, the script predates the invention of worktrees by several years. I
have occasionally played with worktrees, but don't use them extensively
(I'd usually use them for a one-off change, and then remove the
worktree).

I don't think I need anything that fancy. But simply checking "is this
checked out in a worktree" for each branch and then doing "cd
/path/to/worktree && git rebase" instead of just "git rebase $branch"
would be enough, I think.

(I'm assuming the problem you see is just that the directory running
Meta/rebase cannot check out a branch that is checked out in another
worktree).
