`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

# Indentation
|
|
# -----------
|
|
# Coq's syntax is based heavily on keywords and program structure,
|
|
# not based on explicit, unique delimiters, like braces in C-family.
|
|
# So it is difficult to properly indent using only regex...
|
|
# Hence here only a simple mechanism of copying indent is done.
