This code doesn't work for if the battery is not present. It would
also seem useful to represent whether the battery is charging,
discharging or at full capacity by prepending the percentage with ^, v
or =, but this is personal taste. I was just about to set up this sort
of output, planning to just take the ruby battery info parsing code
from Mauricio Fernandez's wmii-ruby.
