When using %? to format a string arg to fmt!(), any single-quotes in the string are escaped, even though single-quotes are not special characters within double-quoted strings.

printfln!("%?", "foo 'bar'");

prints

"foo \'bar\'"

…pub-crate, r=llogiq

ignore `redundant_pub_crate` in `useless_attribute`

changelog: [`useless_attribute`] no longer lints [`redundant_pub_crate`]

As mentioned in rust-lang/rust-clippy#8732 (comment)

> And it turns out I can't even explicitly allow it at the usage site, because then `clippy::useless_attribute` fires (which would also be a FP?), which is deny-by-default.

> ```rust
> #[allow(clippy::useless_attribute)]
> #[allow(clippy::redundant_pub_crate)]
