Description
When using multiline string literal in doctest, rustdoc pads spaces after the newline. The doc renders perfectly fine:
I tried this code:
//! Hello world.
//!
//! # Examples
//!
//! ```rust
//! let s = "
//! Hello
//! World";
//! assert_eq!("\nHello\nWorld", s);
//! ```
//!
//! ```rust
//! let s = r#"
//! Hello
//! World"#;
//! assert_eq!("\nHello\nWorld", s);
//! ```
fn main() {
println!("hello world!");
}
I expected to see this happen: The test should pass.
Instead, this happened: The test failed.
