Subject: bat: find battery status when multiple batteries
X-Git-Url: https://git.madduck.net/etc/awesome.git/commitdiff_plain/ae086776bf94a932719899ec828e002f67ebd098?ds=sidebyside;hp=617675d6c3a7b79d650bfcd52a3c13e8dcdfa459

bat: find battery status when multiple batteries

Battery status was previously assumed to the first battery's status. This is
wrong as it doesn't support the case where the first battery is full and the
second is discharging, therefor showing battery percentage to 100% when the
actual battery percentage is lower.
