Add suggestion to print_with_newline

[killercup]

This code

fn main() {
    println!("");
}

currently (clippy 0.0.177) triggers this:

warning: using `println!("")`, consider using `println!()` instead
 --> src/main.rs:2:5
  |
2 |     println!("");
  |     ^^^^^^^^^^^^^
  |
  = note: #[warn(print_with_newline)] on by default
  = help: for further information visit https://rust-lang-nursery.github.io/rust-clippy/v0.0.177/index.html#print_with_newline

where the suggested replacement is only in the warning: line, but is not a true, auto-applicable suggestion.

Why is changing println!("") to println!() not applicable?

[killercup]

It's not *auto*-applicable (by rustfix) because the lint doesn't use `span_suggestion`. Henri Wiechers <[email protected]> schrieb am Do. 4. Jan. 2018 um 05:18:
