cargo fmt: missing linebreak in error message

[matthiaskrgr]

./target/debug/cargo-fmt -p wasd

The error message is:

[...]
ARGS:
    <rustfmt_options>...    Options passed to rustfmt%

looks like there is a final linebreak missing after the --help output.
(it should be Options passed to rustfmt\n instead of Options passed to rustfmt)

Heya!

Really new to rust, but would like to start contributing small things! I looked into the code, and it seems this could either be solved by adding:

app.after_help("\n").write_help....;

to cargo-fmt/main.rs:98 -- or maybe solving it for everyone in the clap crate. (i.e., if I followed the code correctly and this is using clap)

It would be great if anyone could comment on which approach would be better.

Cheers!

Turns out that the after_help hook adds a newline at the end without having to explicitly writing it, I'll create a PR. :)
