From 02786155dc7f5962242681f53383a54230f76965 Mon Sep 17 00:00:00 2001

Subject: [PATCH] tests: use i3_config arg instead of precisely one
 launch_with_config
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

This way, tests are shorter, and i3test’s invocation of launch_with_config
parallelizes work better, using dont_block => 1.
