fix scroll of charging

The intended change was that you'd get an increase to max energy if
current was sufficiently close to max rather than only when it was
already at max.  It wasn't intended that you'd fail to have current
boosted all the way to max in the case where it wasn't sufficiently
close.  That's fixed here.
