Don't try to print `optarg' (which will be a NULL pointer) if an unknown
command line option was used, as this leads to a segfault on some systems. The unknown option will be printed by getopt(3) anyway. So, simply call print_usage() and exit UNKNOWN via the new usage5() instead. git-svn-id: https://nagiosplug.svn.sourceforge.net/svnroot/nagiosplug/nagiosplug/trunk@1590 f882894a-f735-0410-b71e-b25c423dba1c
