Subject: [PATCH 1/2] edit: propagate correct editor exit code
Date: Fri,  8 Nov 2019 20:20:17 +0000
Message-ID: <20191108202018.15680-2-e@80x24.org> (raw)
In-Reply-To: <20191108202018.15680-1-e@80x24.org>

exit($?) is never correct, since ($? >> 8) is needed to extract
the correct exit code, as other information (e.g. such as signal)
is encoded in $? in addition to the exit code.
