[Nut-upsuser] Bogus shutdown

[Patrick Nolan]

Nut shut down a machine last night when there was no power outage.
When I came in this morning, the UPS was turned off, but it turned on
cleanly and passed its self-test.  The battery was at 62% when I
first checked it, and it's up to 63% now, about 20 minutes later.

The UPS is a Tripp-Lite AVR550U.  I'm running nut version 2.0.3.
I expect to be told to update to a newer version and to quit
using hidups.  Is there anything else?

Here's the relevant section of the log:
