Drat, you're right. I'd been mainly looking at the include code, and had missed that those functions' versions in `lib/messageformat.dev.js` were missing a `var` prefix. So they end up as globals, when they really shouldn't and needn't. The compiled code is fine, though, there the single-letter functions only exist within the wrapping anonymous function. Do you want me to fix this and do a pull request, or will you do it yourself?
