As long as we make it consistent on both sides of the '=>' (and document
it, too), then I don't really care either way. Currently you have to use
quotes to get an empty key, so I thought it natural to that you should
have to quote to get an empty value.

I've attached a modified version of Tom's patch which also allows empty
keys.
