bug#7934: 24.0.50; Nextstep: Can't copy and paste null characters

> Fixed in trunk.

Thanks, Jan.  But I wonder why this bug manifested itself in the "C-k
C-y" case, which I thought would not fetch the selection from the OS but
would short-circuit it and take it directly from the kill-ring (which
has the advantage of preserving the unibyte/multibyte distinction, the
text-properties, ...).
