Drew Adams points out that we need an (interactive) form between
isearch-yank-kill-as-regexp's argument list and its doc string.

He also reports:

I suspect it has something to do with the global binding of M-z to
zap-to-char and/or the squirrely business with isearch-other-meta-char,
which I don't understand.  Does the problem go away if you bind a
different meta-character or a control-character to
isearch-yank-kill-as-regexp?
