One other alternative history search widget

[Sebastian Gniazdowski <sgniazdowski@xxxxxxxxx>]

Hello
I've adapted the earlier announced zcurses based selection list so
that it works from within ZLE. It can be bound to the typical "^R" key
combination to provide history search. It uses whole screen and
highlights matches, what can be seen here:

So, that's one other alternative history search widget, available here:
https://github.com/psprint/zsh-navigation-tools

One problem is that it puts multi line history entries into one line,
introducing '\n' where the newlines should be.

Best regards,
