The only problem with this is that I'm pretty sure that I was unable to
do the += unless counts[c] already existed (which makes sense, since
otherwise it's nil).  That makes the code messier, because you need a
test.

Am I wrong?  If not, can you see a neat way to get it to work, without
using the test?
