journalctl: specify "--unit=" and "--user-unit" multiple times
Previously only one "--unit=" or "--user-unit" could be specified. With this patch, journalcrtl can show multiple units. $ journalctl -u systemd-udevd.service -u sshd.service -u crond.service -b -- Logs begin at Sa 2013-03-23 11:08:45 CET, end at Fr 2013-04-12 09:10:22 CEST. -- Apr 12 08:41:37 lenovo systemd[1]: Started udev Kernel Device Manager.
