Thanks, now this feature is getting into good shape, and it seems soon
your branch will be ready for merging.

Don't hold out too much hope on enabling this feature by default.
Even in zsh this completion style is not enabled by default,
only adding "zstyle ':completion:*' menu select" enables it.

Also in Emacs even less intrusive icomplete-mode is not enabled
by default.

For example, currently when the completions buffer is displayed,
C-r is still available for searching through the previous history.
But when this new mode is enabled, it's more useful to allow C-r
to search in the completions buffer, that works well with your
latest commit.

IOW, the main difference of this feature is that typing TAB
enables a special mode for selecting a completion, and disables
history navigation and motion keys in the minibuffer.

Yes, these are two diverging roads.  So we need to try both, identify
their advantages/disadvantages to decide what path/patch to follow.

With c7c47e78e6, all present motion keys are still available in the
completions buffer, but are all keys that used to exit still handled?

Also setting buffer-local cursor-in-echo-area to t in the completions
buffer provides a better look and feel of editing in the minibuffer
(like you disabled mode-line).
