Log message:
On ESC-y ESC-y (yank-pop), also check that there is something to
insert (some text has been killed before). from otto@, fix PR/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.
