Synchronize with Cargo output changes

[sanxiyn]

For example, 1.2 have

$ cargo new hello_cargo --bin
$ cd hello_cargo

But rust-lang/cargo#2921 added status message to cargo new. So it should be:

$ cargo new hello_cargo --bin
     Created binary (application) `hello_cargo` project
$ cd hello_cargo

More generally, this could happen again, and it would be nice to check this automatically.

I totally agree, and I think this is going to end up being the same as #126, even though that one talks more about error messages, so I'm going to close this as a duplicate of that one. Thank you for the report, though, we'd rather have too many reports than too few!! ❤️
