master 46a49b748e: Work around `&' dired command when using the fish shell

[Lars Ingebrigtsen]

branch: master
commit 46a49b748eaf5553a6eb45215b14baebc090b33b
Author: Lars Ingebrigtsen <larsi@gnus.org>
Commit: Lars Ingebrigtsen <larsi@gnus.org>

    Work around `&' dired command when using the fish shell
    
    * lisp/dired-aux.el (dired-shell-stuff-it): Add a space before
    &wait; this apparently makes the `&' command work with the fish
    shell (bug#57472).
