Subject: [PATCH] logs-show: fix corrupt output with empty messages
If a message had zero length, journalctl would print no newline, and
two output lines would be concatenated. Fix. The problem was
introduced in commit 31f7bf199452 ("logs-show: print multiline
messages"). Affected short and verbose output modes.
Before fix:
