Subject: [PATCH] systemctl: allow set-property to be called with a glob
 pattern
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We call "systemctl set-property … Markers=+needs-restart" and this should
also work for globs, e.g. "user@*.service" or "syncthing@*.service".

(cherry picked from commit 23a0ffa59f9cb26c4b016c9fd1a3a70da2607f61)
