cargo run with stdin input will not work - add to Gotchas?

[respeccing]

Unless I'm missing something, there's a difference between running rustfmt directly(works) versus running it via cargo run --bin rustfmt -- (doesn't output formatted program, if input is stdin)

$ cargo build
...
$ echo 'fn main(){}'| ./target/debug/rustfmt
fn main() {}
$ echo 'fn main(){}'| cargo run --bin rustfmt --
     Running `target/debug/rustfmt`

(that Running part is on stdout, but can add --quiet flag to cargo run to avoid it, that's not a problem)

cargo 0.10.0 (132b82d 2016-03-19) (from 16 days ago)

This seems like a cargo issue though... eg. not properly redirecting stdin to executed program?
If this cargo issue won't be fixed, may I suggest adding this to Gotchas?

EDIT: Quick look: This looks like it should've fixed it rust-lang/cargo#268 but apparently it didn't...

EDIT2: The issue is this: rust-lang/cargo#2530

This was fixed in cargo (5 days ago)
rust-lang/cargo#2530 (comment)

My bad, I was using an outdated version of cargo ;-)

Just tested it to have been fixed.
