Hi Juri,

Correct.  That is the way M-y works now, so that this would not be a
new problem.  Besides, that problem is quite minor, IMO, because:
* The common case would be to yank the last or close-to-last entry
from the ring, so that no (or very few) extra "undo" movements would
be necessary.
* In the rare cases of yanking and old entry *and* then wanting to
revert it, users would always have the quick option of deleting the
region (which as you now is updated in every yank operation).

So, i think that the drawbacks are much smaller than the advantages.

Yes, I also think so.  So this point would make little difference, but
anyway large entries would be shown even better in the buffer, because
there would be normally more visual space.

As I've said above, I think that the common case would imply one or
very few "M-p"'s.  Besides, typing 2 or 3 times the same key is almost
as quick as typing it only once.  Therefore, IMO the extra <RET> would
really make a difference.
