P.CMT.02 Comments should have a width limit

[Description]

The width of each comment line should not be too long and needs to be set at a certain width, no more than 120, which help improve readability.

In rustfmt, the comment_width with wrap_comments configuration item can automatically split comments that exceed the width limit into multiple lines.

Note: The use_small_heuristics configuration item of rustfmt does not include comment_width.

[Bad Case]

#![allow(unused)]
fn main() {
// Bad
// Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
}

[Good Case]

When comment_width=80 and wrap_comments=true.

Note: Here wrap_comments does not use the default value and needs to be configured to true.

#![allow(unused)]
fn main() {
// Good
// Lorem ipsum dolor sit amet, consectetur adipiscing elit,
// sed do eiusmod tempor incididunt ut labore et dolore
// magna aliqua. Ut enim ad minim veniam, quis nostrud
// exercitation ullamco laboris nisi ut aliquip ex ea
// commodo consequat.
}
