## Message

```
docs: Improve documentation of ensure final new line on save (#25960)

The function ensure_final_newline in buffer.rs has this explanation:
Ensures that the buffer ends with a single newline character, no other
whitespace.

The documentation wasn't explaining well that we actually remove any
lines containing only whitespace and keep only 1 line at the end of a
buffer.

Release Notes:

- N/A
