From OpenBSD: 

revision 1.21
date: 2003/08/02 19:26:15;  author: fgsch;  state: Exp;  lines: +4 -2
On ESC-y ESC-y (yank-pop), also check that there is something to
insert (some text has been killed before). from otto@, fix bug report 3384.

On yank-pop error (no yank before), reset the index to killstack so
another yank-pop does not mangle the prompt if nothing was yanked, and
to avoid replacing a text when it shouldn't
(yank <something> yank-pop yank-pop).
otto@ ok.
