Added the ability for newsyslog to archive logs with
a timestamp, in 
addition to the normal log rotation.  
	In addition, the number of log files to maintain
(numlogs) was not 
checked and caused newsyslog to hang when it was set
to a negative value 
in /etc/newsyslog.conf.  The included patch now checks
this value.
	The man page was also updated to describe the new
functionality.

Fix:

How-To-Repeat: 	Set the number of log files to maintain to a negative
value in 
/etc/newsyslog.conf and run newsyslog.  It will not
complete.
