`x` is often criticized as hard to predict due to its slightly complex behaviour of selecting next line if the current one is fully selected. Change `x` to use the previous `<a-x>` behaviour, and change `<a-x>` to trim to fully selected lines as `<a-X>` did. Adapt existing indentation script to the new behaviour
