From 3d411afabc9a96f41d47c07d6af6edda3d29ec92 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Carlo=20Marcelo=20Arenas=20Bel=C3=B3n?= Date: Tue, 5 Oct 2021 00:46:48 -0700 Subject: editor: save and reset terminal after calling EDITOR MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When EDITOR is invoked to modify a commit message, it will likely change the terminal settings, and if it misbehaves will leave the terminal output damaged as shown in a recent report from Windows Terminal[1] Instead use the functions provided by compat/terminal to save the settings and recover safely.
