rustfmt producing invalid code

[mlafeldt]

rustfmt 0.8.4 and current HEAD will format this:

                assert!(Syscheck::new(&mut vec![String::from("one"), String::from("two")]).is_err());

To this code, which can't be compiled:

                assert!(
                    Syscheck::new(&mut vec![String::from("one"), String::from("two")]).is_err(),
                );

We're using the config at https://github.com/rust-lang-nursery/rustfmt/blob/master/rfc-rustfmt.toml

I think this is fixed on the current master. It may exceed max width, but will not produce invalid code.

I installed current master (272b0b6) via Cargo and it did not fix the issue though.

Thanks for your reply! Unfortunately I could not reproduce the issue with my environment. Are you sure you are using the rustfmt from the current master? rustfmt --version should give something like 0.8.4-nightly (272b0b6 2017-06-12). Either way, I added commit to #1654 and it should fix this issue.

Closing since this if fixed on the current master.

True! Thank you.
