Oops, yes; I should have made the PR from a branch, so additional commits to master didn't creep in.  I'll fix that.

In case you're curious, I was pointing to a Handlebars commit that included support for CommonJS out of the box (https://github.com/wycats/handlebars.js/pull/537), which has been merged into their master, but a new version has not been published to NPM.
