seems to only return one value so seems to get odd results if I
specify something like
get_longest("aaabcccbbb")
which at least here tells me that "c" is the longest run, even though
aaa, bbb, and ccc are all runs of length 3. The OP didn't specify
what should happen in that case, so it would need some clarification.
