std::fmt module documentation error

See http://doc.rust-lang.org/std/fmt/index.html

e.g. http://doc.rust-lang.org/src/collections/fmt.rs.html#365-369

'0' - This is used to indicate for integer formats that the padding should both be done with a 0 character as well as be sign-aware. A format like {:08d} would yield 00000001 for the integer 1, while the same format would yield -0000001 for the integer -1. Notice that the negative version has one fewer zero than the positive version.

It seems what instead of {:08d}, {:08} is required.

E.g. (http://is.gd/oL48zO)

fn main() {
    println!("{:08d}", 10i32); 
}

produces

<anon>:2:24: 2:29 error: unknown format trait `d`
<anon>:2     println!("{:08d}", 10i32);

I tried to search already reported issue, no luck.
If it's something really worthy, I might try to come up with PR to fix it.

[leonardinius]

So, does it qualify for a proper PR?

I'm new in Rust ecosystem and I thought it could be a good way to both contribute back and start small, e.g. understand how the whole process works ... ;)

Edit s/smart/small/

[steveklabnik]

yes, absolutely! If you have the time, that'd be great.

You can check out https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md for full details, but basically, just make a pull request :)

[leonardinius]

Great, will do it some time during this week.
