After a few fixes (thanks to Pip Cet for finding several bugs!) and 
writing up the documentation, this has now merged to the master branch. 
I have a few more enhancements in mind, but what's here covers the basics.

I intentionally merged this early in the release cycle for Emacs 32 so 
that there will be plenty of time to find and fix any bugs in this, as 
well as to give me a sizable window of time to make incompatible changes 
before we commit to a stable API when 32.1 releases.
