Well, not one to drop something I have in mind to do, I kept whacking at this problem. In the past, I have saved these find/replace pairs to a file so they can be reused. I decided there was no harm in just using that file as the input/display of what the find/replace pairs are. So, after a couple of hours of twiddling around, I came up with something that I think will work well enough for me, and I thought I'd share it just in case it's of interest to anyone else (either for its intended use or an example of how to do something).https://gist.github.com/1519543
Since I'm pretty new to Python, I'd appreciate any suggestions on how to make the code better.
