Better than leaving *doo doo* in a file
Sometimes, but not always. I can think of plausible cases where I'd
rather have a partial copy than no copy at all. As an extreme example,
if I'm doing 'cp /dev/tty A', I do not want A removed on interrupt
even if A has already been truncated and overwritten,
as A contains the only copy of the data that I just typed in by hand.
But we could add an option to 'cp' to have this behavior.
Perhaps --remove-destination=signal? That is --remove-destination
could have an optional list of names of places where the destination
could be removed, where the default is not to remove it, and
plain --remove-destination means --remove-destination=before.

I think you misunderstood the problem.
Perhaps I did. But could you explain the problem then? For example,
how would the proposed "cp --remove-destination=signal A B"
not address the problem?
