Subject: [PATCH 09/11] lei add-external: completion for existing URL basenames
Date: Tue,  2 Feb 2021 22:11:41 -1000	[thread overview]
Message-ID: <20210203081143.24424-10-e@80x24.org> (raw)
In-Reply-To: <20210203081143.24424-1-e@80x24.org>

Given the presence of one external on a certain host or prefix
path, it's logical other inboxes would share a common prefix.
For bash users, attempt to complete that using the "-o nospace"
option of bash
