[Nut-upsuser] NUT no longer works after 2.7 -> 2.8 upgrade

My email client (Thunderbird) does not truncate, but it does wrap.  The 
truncations come from the way systemctl runs its output through a pager. 
When I copy-paste from the bash session, it truncates at the right edge 
of the window.   I need to use the --full and --no-pager options to get 
the full text, which will be wrapped as needed.

Here is the output from upsd -DD:

===================================
[root at mythtv ~]# upsd -DD

==============================

Just for grins, I edited /etc/ups/upsd.conf to uncomment the STATEPATH 
line.  I set it to /run/nut.  When I ran upsd -DD again, it was still 
looking at /var/run.  However!  It successfully connected to the 
cyberpower device.  Upsc returns good information.
