format!(...) with only constant arguments #1601
Description
Examples from my own code: https://github.com/trailofbits/cargo-unmaintained/blob/c360340d8be83eb612abe90c5950f43bb25403ee/tests/ci.rs#L172-L174
&format!("{}/**/*.md", env!("CARGO_MANIFEST_DIR")),
&format!("{}/**/*.yml", env!("CARGO_MANIFEST_DIR")),
&format!("!{}/target/**", env!("CARGO_MANIFEST_DIR")),^ These could be rewritten to use concat!(..).
