	+===========
	+
	+Description
	+-----------
	+This patch implements a function that displays the status and capacity of
	+all present batteries (only supported for Linux).
	+
	+The order of the format identifiers is hard-coded: battery number (%u),
	+state (%s), capacity (%s). Example:
	+"[BAT%u: %s%s]" -> [BAT0: +58]
	+
