I think I would skip this patch. If the BSD expr syntax from the patch
also works with GNU expr, consider submitting it upstream instead.

It's not necessarily /var/log/messages depending on config (and syslogd
would be writing to /var not ${LOCALSTATEDIR} in the extremely unlikely
case somebody rebuilt this with a different LOCALSTATEDIR).
I would simply go with this:
"UseLogging 2" uses syslog.
Rest looks ok with me.
