Warn suspicious_else_formatting when a function using "tracing crate" has a comment containing "else".

[hotate29]

Lint name: suspicious_else_formatting

I tried this code:

use tracing::instrument;

#[instrument]
async fn func1() {
    // a
    // else
}

#[instrument]
async fn func2() {
    ()
    // else
}

#[instrument]
async fn func3() {
    let _ = ();
    // else
}

I expected to see this happen: No warning

Instead, this happened:

warning: this is an `else {..}` but the formatting might hide it
 --> src\lib.rs:4:17
  |
4 |   async fn func1() {
  |  _________________^
5 | |     // a;
6 | |     // else
7 | | }
  | |_^
  |
  = note: `#[warn(clippy::suspicious_else_formatting)]` on by default
  = note: to remove this lint, remove the `else` or remove the new line between `else` and `{..}`
  = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#suspicious_else_formatting

Same warning for func1 to func3.

With version 0.1.28 of tracing.

May be the same as this
#6249 (comment)

[giraffate]

It seemed to be addressed by tracing at tokio-rs/tracing#1617, and released in new version tokio-rs/tracing#1621.

Thank you for telling me! Then I think I will close this issue as it is not needed.
