Subject: [PATCH 3/9] terminal: make the code of disable_echo() reusable
Date: Sat, 21 Dec 2019 22:41:54 +0000	[thread overview]
Message-ID: <7631c1ea8c82154581eaaed9dcc278a011897282.1576968120.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.175.git.1576968120.gitgitgadget@gmail.com>

From: Johannes Schindelin <johannes.schindelin@gmx.de>

We are about to introduce the function `enable_non_canonical()`, which
shares almost the complete code with `disable_echo()`.

Let's prepare for that, by refactoring out that shared code.
