Strictly we'd want a version of Copy that filled the source with rubbish
(or bit flipped it it or something), as Copy is for non-overlapping
cases. Move would have to be more clever and selectively trash only the
non-overlapping parts.

But it's a suitably evil idea. If no-one gets there first I'll try it,
once I acquire some copious free time.
