Subject: [PATCH] Add support for multiple batteries

Hello, I have a laptop with two batteries and I want to display them both. Your script has support for 2 batteries in theory, i.e. it prints two strings with status. But only the first result is used. I propose concatenating two results in one string and echoing *it* instead. That way 2 batteries are displayed inside one dwm block.
