Module Name:    src
Committed By:   kre

Modified Files:
        src/bin/kill: kill.1

Log Message:
Note that negative pid args are permitted (indicating to send to the pgrp
abs(pid)) and indicate that -- is (strictly) needed if the first pid arg
(there often is only one) is negative - though this implementation works
without it if a signal to send has been explicitly given, but whereas
'kill 1234" is valid (send SIGTERM to pid 1234) "kill -1234" will generate
a usage error from the attempt to send signal 1234 to nothing, to send
SIGTERM to pgrp 1234 it needs to be "kill -- -1234" (or "kill -s term -1234").

While here do a couple of markup improvements, and allow for the
possibility that users might be running the builtin kill from some
shell other than csh or sh.
