Just a thought for your consideration ...

I am wondering if this follows the principle of least surprise, at
least with regard to logging.  I was initially baffled why this release
was not logging anything to the system log and thought it to be a bug.
I then realized that the config file's "Log notice syslog" had been
disabled by the command line's --log "notice stdout", which I was piping
to a script.  Expected behavior returned when I changed --log to --+log.

Also, as best I can figure out, this change is not reflected in the man
page (revised Dec 8, 2011).  In addition to skimming the man page, I
searched for both "+" and "plus".

Best regards,
