Ich sehe nicht, warum man den Pattern dafür so verändern sollte.

Das sollte funktionieren. Siehe 'man zshexpn': x# vs x##.

Ich werde das nun committen, inklusive Close: Zeile für diesen Issue.
Wenn der Patch das ganze nicht lösen sollte bitte melden.

Ab Release >=1.4-1 von acpi werden keine Leerzeichen beim Output mehr am Anfang
der Zeile angezeigt. Aus vorher "       battery..." wurde "battery....". Alles in Zeile 1077 der
zshrc. Vorschlag zur Lösung ist:
PERCENT="${${${(ws: :)${(M)${"$(acpi 2>/dev/null)"}##*Battery*}}[4]}%\%}"
