As I apparently did not state clearly enough, one would switch off
visual line mode during recording already (after all, during recording
one tries to achieve the effect that replay should have).

Yes, this will means that the same key sequence outside of macro
recording/replay and inside of it will have different effects.

I readily agree that this is ugly, and if you want to, even "wrong".
The alternative is "useless".  Which serves no point.
