The discharging `format` put a single space between the icon span and
{capacity}%, but the battery-bar glyphs carry almost no right bearing,
so the state read cramped — while charging/plugged use glyphs with their
own spacing and looked fine. Widen only the discharging line to two
spaces across all four themes that ship their own bar (boreal,
summer-night, summer-day, executive-slate).
