I have one template in which I set search to contain the whole code block. This is because I had one edit at the very beginning and one edit at the very end. It works fine but now I'm thinking it would make sense to have two mods based on the original template. One for the beginning code change and one for the ending code change. The idea being that the bulk of the code would not be in the mod and there would be less chance of a conflict when upgrading.
