Let commands take over the terminal?

Is it possible to yield control of the terminal to each command when it runs? This would open up a bunch of new possibilities.

1. Commands that use $EDITOR or $PAGER.
* From an `ls` view, you could bind `vim $0` or `less $0` to a key. The editor would take over the terminal temporarily; when you quit the editor you'd be back in the same lazycli session.
* From the `git status` view, you could run `git commit` and let the commit-message editor take over temporarily.
* From `git log` you could run `git show --patch` to preview a commit.
2. Commands that prompt for a second argument.
* From `ls`, you could bind `r` to `mv $0 $(read)`. Then to rename `foo` to `bar` you'd select `foo`, and type `r bar`.
* Similarly, from `git branch`, you could bind `git branch mv $0 $(read)`.

I'm not sure how this would be implemented, but it might be similar to vim's `:!` command. As a (contrived) example, when you run `:!htop`, htop takes over the terminal; when you quit htop you end up back in vim again.
