Subject: [RFC PATCH 2/2] editor: save and reset terminal after calling EDITOR
Date: Sat, 2 Oct 2021 08:36:54 -0700 [thread overview]
Message-ID: <20211002153654.52443-3-carenas@gmail.com> (raw)
In-Reply-To: <20211002153654.52443-1-carenas@gmail.com>
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 as shown in microsoft/terminal#9359.
Instead use the recently added {push,pop}_term() functions to save
the terminal configuration and recover safely.
