You have these two situations:

print_log(LOG_DEBUG, "doing this and that....\n");

if (debug) { /*
 gather_some_data_that_is_very_expensive_operation_to_do_all_the_time();
 print_log(LOG_DEBUG, "print those extra data\n");
}

as it is now, it would basically be an alias to set logpriority to DEBUG
but enables people to execute debugging code conditionally and as I
wrote it is an easy keyword to remember compared to
syslog_priority/logpriority.
