Subject: [PATCH v3 4/4] sequencer.c: don't die on invalid cleanup_arg
Date: Thu, 7 Mar 2019 01:58:35 -0800	[thread overview]
Message-ID: <68ec2b7cd7457e9bcd3f6f211774457c73ef8646.1551951770.git.liu.denton@gmail.com> (raw)
In-Reply-To: <cover.1551951770.git.liu.denton@gmail.com>

When get_cleanup_mode was provided with an invalid cleanup_arg, it used
to die. Warn user and fallback to default behaviour if an invalid
cleanup_arg is given.
