From f83d7cc312b5e8c82052b484998fa26d4af35b36 Mon Sep 17 00:00:00 2001 From: Stefan Kangas Date: Tue, 12 Jul 2022 12:11:43 +0200 Subject: Make remote-shell-program default to ssh only * lisp/files.el (remote-shell-program): Default to "ssh" only. The other commands in this list have severe security issues, and it is easy enough for users to customize them manually if they want to.
