From d5a9ac31ff7e851e88f84f7cb02cf6f8f296c125 Mon Sep 17 00:00:00 2001

Subject: [PATCH] fix: explain an installation found in the plain output, and
 take over one started from docker-compose.yaml

The plain output, used in a terminal smaller than 80x22, never showed a question's help: an
installation found was offered without saying what it was or why it could not be taken over.

An installation started from docker-compose.yaml, compose.yaml or compose.yml is now read from
that file and taken over; its first backup or upgrade renames it docker-compose.yml. A missing
compose file or .env, and one root cannot read, each get their own explanation. One already at
the version the installer installs is taken over without the word upgrade.
