kill -PID fixed

Browse Source 
Bug-Debian: http://bugs.debian.org/688731

kill would not permit negative PIDs and thought they were options. kill
now explicitly checks for unknown options and if they are numeric
assumes they are negative PIDs.  The first negative PID stops any
further option processing.
