Subject: [PATCH 1/3] lei forget-external: split into separate file
Date: Sat, 25 Sep 2021 08:49:43 +0000	[thread overview]
Message-ID: <20210925084945.15899-2-e@80x24.org> (raw)
In-Reply-To: <20210925084945.15899-1-e@80x24.org>

This was written before we had auto-loading, and forget-external
should be a rarely-used command that's not worth loading at
startup.  Do some golfing while we're in the area, too.
