Add tests for Rust 1.47.0
This patch adds unit tests for the new Rust 1.47.0 release.  Except for
the new Notable Traits section, we’re already parsing the output
correctly.

anyhow Macro anyhow::anyhow rusty-man
SYNOPSIS
macro_rules! anyhow {
($msg:literal $(,)?) => { ... };
($err:expr $(,)?) => { ... };
($fmt:expr, $($arg:tt)*) => { ... };
}
DESCRIPTION
Construct an ad-hoc error from a string.
This evaluates to an `Error`. It can take either just a string, or a format string with
arguments. It also can take any custom type which implements `Debug` and `Display`.
# Example
use anyhow::{anyhow, Result};
fn lookup(key: &str) -> Result<V> {
if key.len() != 16 {
return Err(anyhow!("key length must be 16 characters, got {:?}", key));
}
// ...
}
