handle_change_delete() has a block of code displaying one of four nearly identical messages. Each contains about half a dozen variable interpolations, which use nearly identical variables as well. Someone trying to parse this may be slowed down trying to parse the differences and why they are here; help them out by adding a comment explaining the differences. Further, point out that this code structure isn't collapsed into something more concise and readable for the programmer, because we want to keep full messages intact in order to make translators' jobs much easier.
