New sysfs battery interface has a flaw.

Suppose I removed battery from the system, and then booted it.
then gnome power manager has no idea that my system has battery, and
thus it hides battery settings.

It also has a bug that prevents it from hiding battery icon, when I
unplug the battery, in other words, it isn't prepared for battery to
disappear.

I think it would be nice to keep /sys/class/power_supply/BAT0/ even if
battery isn't present.

btw, there is /sys/class/power_supply/BAT0/present, thus maybe this is
just a bug?

Best regards,
