Some trait methods don't appear in the docs of types that implement the trait

What needs to be fixed?

Here's a specific example: the doc for Bufreader doesn't include the method lines in the Bufreader impl section. Other methods like has_data_left are documented. Both has_data_left and lines are default methods, and yet only one of them is described.

It's causing an issue because I can't find if a method is implemented on a structure by searching through the structure's documentation.

Page(s) Affected

https://doc.rust-lang.org/std/io/struct.BufReader.html#impl-BufRead-for-BufReader%3CR%3E

I believe I've seen the same issue elsewhere, but I don't have an example to hand right now.

This is a repository for the main website (not docs), rustdoc bugs are rust-lang/rust.

I suspect this has to do with the Sizes bound.
