Oh, that's true. (I guess maybe we could add a way to do that, and other prefix commands could work that way too. But that would be a big effort - and worth talking about on emacs-devel) > If you agree there is no other way to implement this than next-default-directory, > then I could bring up the discussion on emacs-devel. Yes, seems like that's the only way.
