try new code function

[Le Wang]

Hi all,

I have this function that comments out a selected region like so

;; -old-code-marker

;; ... old code

;;-test-code-marker

;;-end-test-code

So you select some "old code" to comment out this way, and the next time you invoke the function, it asks you whether you want to keep the old code or use the new code and makes it so.

It's fairly trivial, would anyone find this useful if I packaged it?  Does anyone know of anything similar?
