[Nut-upsuser] Can't get 'load.off' to turn off power to the PC: CyberPower 1200AVR

Never mind that remark. Changing variables in nut-2.2.0 is broken for
subdrivers that define multiple HID paths for the same NUT variable. It
will only use the first HID path it finds, whether or not it is supported
on the connected UPS. Since the apc-hid.c subdriver only has one mapping
for 'battery.charge.low' this is OK, but it has no less than three for
'ups.delay.restart' and the one you need is the third.

So forget about changing 'ups.delay.start', it won't work with nut-2.2.0
(the development version should work however).
