master 6996204 2/2: Fix wdired-do-perm-changes when over Tramp

[Lars Ingebrigtsen]

branch: master
commit 6996204dd036650b7e1e7f9580055fefb033abe5
Author: Tino Calancha <tino.calancha@gmail.com>
Commit: Lars Ingebrigtsen <larsi@gnus.org>

    Fix wdired-do-perm-changes when over Tramp
    
    * lisp/wdired.el (wdired-do-perm-changes) Use set-file-modes
    instead of external program (bug#39284).  This fixes the problem
    of passing the wrong argument to the external chmod.
