Extra spaces in the format_into documentation

Summary

use core::fmt::NumBuffer;

let n = 0usize;
let mut buf = NumBuffer::new();
assert_eq!(n.format_into(&mut buf), "0");

let n1 = 32usize;
assert_eq!(n1.format_into(&mut buf), "32");

let n2 = usize :: MAX;  // Extra spaces
assert_eq!(n2.format_into(&mut buf), usize :: MAX.to_string());  // Extra spaces

Possible patch:

-#[doc = concat!("let n2 = ", stringify!($Signed::MAX), ";")]
-#[doc = concat!("assert_eq!(n2.format_into(&mut buf), ", stringify!($Signed::MAX), ".to_string());")]
+#[doc = concat!("let n2 = ", stringify!($Signed), "::MAX;")]
+#[doc = concat!("assert_eq!(n2.format_into(&mut buf), ", stringify!($Signed), "::MAX.to_string());")]
