Some method signatures in documentation missing self

[gsingh93]

An example: http://doc.rust-lang.org/std/string/struct.String.html#method.append

Seems to be the ones that take self and not &self.

As @tomjakubowski notes in #15889, this only affects reexported methods, e.g. the original definition is fine: http://doc.rust-lang.org/collections/string/struct.String.html#method.append

Seems relevant:

rust/src/librustdoc/clean/mod.rs

Lines 875 to 877 in 43d84bf

	if names.peek().map(|s| s.as_slice()) == Some("self") {
	let _ = names.next();
	}

        if names.peek().map(|s| s.as_slice()) == Some("self") {
            let _ = names.next();
        }

This occurs in all of these cases:

• Methods taking self on re-exported structs.
• Methods taking self on re-exported traits.
• Trait methods taking self on impls of re-exported structs
• Default implementations of provided trait methods taking self on local impls of external traits.

But not:

• Required trait methods taking self on local impls of external traits.
• Overridden implementations of provided trait methods taking self on local impls of external traits.
