O.K., I mounted my USB drive, went back in my archived stuff and found 
this "exclude" file:
[root at mavis ~]# cat /media/OT*/extra/FC1*/home/rj/nobackup
[root at mavis ~]#
You can use this rather than several --exclude entries on the command by 
using the option -X <exclude-file-name>.
Whatever suits you just tickles me plumb to death.
