The only part I'm not sure about here is what to do with negative
numbers.  I'm sure there's some representation which gives the desired
result when sorted lexicographically; Doug?

Something that handled a variety of date formats would be nice too.
The standard DateFormat handles nn/nn/nn[nn], but not nnnn-nn-nn or
nn.nn.nnnn or any of the others.  I don't want to get carried away
here with a pluggable date parser -- I just think we should choose
some reasonable representation and call it good.

But we're still stuck on date formats with time -- right now, we're
using whitespace as delimiters in the range -- which means that dates
  2002-01-01 1:35 PM
are no good unless enclosed in quotes.
