Maxime Coste ef8a11b3db Make x just select the full lines
`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
