Log sinks: syslog, a file, or stderr.
Lines written to a file or to stderr keep autossh’s format,
%Y/%m/%d %H:%M:%S rash[pid]: message (autossh.c:1783-1819), so anything
already parsing autossh logs keeps working.
The syslog call is always syslog(level, "%s", msg). autossh’s fallback path
passes the message as the format string (autossh.c:1797), which misbehaves
on any log line containing a %.
