let s = "foo
bar";
-assert_eq!("foo\n bar", s);
+assert_eq!("foo\n bar", s);
```
The second, with a `\`, trims the spaces and the newline:
prog.push_str(&everything_else);
} else {
prog.push_str("fn main() {\n ");
- prog.push_str(&everything_else.replace("\n", "\n "));
+ prog.push_str(&everything_else);
prog = prog.trim().into();
prog.push_str("\n}");
}
