	handle-switch-frame instead of select-frame; it has been renamed.

(isearch-unread): Don't call it here.
(isearch-mode-map): Bind the ASCII-equivalent function keys.

For Emacs 19, use listify-key-sequence.
If not Emacs 19, assume they are a meta sequence.
(isearch-other-meta-char): Pass the whole key sequence.
(isearch-other-control-char): Make this alias for ...-meta-char.

New arg no-recursive-edit, always non-nil for interactive call.
Rename first arg, and set it right in interactive call.
(isearch-forward-regexp): Likewise.
(isearch-forward, isearch-backward): Likewise no-recursive-edit.

	* vip.el (vip-escape-to-emacs, vip-prefix-arg-value,
	vip-prefix-arg-com): Use unread-command-event instead of
	unread-command-char; respect its new semantics.
	* isearch-mode.el (isearch-update, isearch-unread): Same.

	replaced by...
	(isearch-gnu-emacs-events): non-nil if should expect events in the
	style generated by GNU Emacs 19.  Set if set-frame-height is
	fboundp; this is true on any GNU Emacs 19, whether or not it was
	compiled with multiple frame support.
	(isearch-mode-map): Test isearch-gnu-emacs-events instead of
	isearch-frames-exist to see if we should bind switch-frame events.
	(isearch-update): Test isearch-gnu-emacs-events instead of
	isearch-frames-exist to see if unread-command-char's quiescent
	value is nil or -1.

Bind cursor-in-echo-area only around read-char/allocate-event.

Explicitly bind control characters at that level.
