But, for various other reasons, we do need to provide a way for an interactive spec to indicate the precise form of the command recorded in the command history. We currently have some hacks, for example to try and recognize when two arguments correspond to the region boundaries and replace the corresponding numbers with (point) and (mark), but those are brittle and need to be replaced by something more reliable and flexible.
