Well, in the sysmerge use-case, you see the first line showing the $OpenBSD$ prompt usually. That's often when you realize your terminal is really small, and you will miss the next lines. The $OpenBSD$ line is reasonably unambiguous, as the rev number is fairly prominent. The next ones will need the space. Admittedly, it could be smarter, and react during actual user interaction, or offer to redraw the last block with a specific command ?
