Last character in log lines is space (2 replies)

Hello,

I am writing haproxy (1.6.9) logs via syslog:

global
log /dev/log local0 debug alert


local0.* /var/log/haproxy.log


I just noticed that last character of each line is space:

Log lines from other sources do not have this trailing space.

Am I missing something obvious?

Thanks.
