Subject: [PATCH v13 07/36] docs/dyndbg: update examples \012 to \n
Date: Wed, 8 Apr 2026 14:01:42 -0600 [thread overview]
Message-ID: <20260408200211.43821-8-jim.cromie@gmail.com> (raw)
In-Reply-To: <20260408200211.43821-1-jim.cromie@gmail.com>
commit 47ea6f99d06e ("dyndbg: use ESCAPE_SPACE for cat control")
changed the control-file to display format strings with "\n" rather
than "\012". Update the docs to match the new reality.
