From bcb06b5f58aee62521737a60703c44d41405710c Mon Sep 17 00:00:00 2001 From: Ian Campbell Date: Fri, 25 Jan 2019 13:10:59 +0000 Subject: [PATCH] Rework `docker info` output to be more like `docker version` That is, reindent the two sections by one space. While the code was done by hand the `.golden` files had the extra space inserted with emacs' `string-insert-rectangle` macro to (try to) avoid possible manual errors. The docs were edited the same way.
