I'm still not convinced this change is worth making now. On X, even
with clipboard enabled, the actual copying to the clipboard is only
performed if another application requests it. Andrew Innes suggested
many years ago that the W32 clipboard should work the same way, but
noone has picked up that job yet. I don't know which way Mac does it,
but that can probably be modified to use delayed copying if it does
not already. So we are talking about reducing the functionality of
keyboard macros to get around a performance problem that does not
exist on the most important platforms, and that we know can be fixed
on others.
