Hi Jim,

Unless I'm missing something, an alternative way to achieve your
templatings stuffs that you've got here is to use yasnippet:

You can setup templates rather easily for various languages (not just
sweave), and making new templates are pretty easy (no elisp required

Here's a video of it in action:

The first ~ minute is how to install it, which you can skip if you're
in a hurry and just want to check it out.

Hope that helps,
