Title: Guide: show Rust has range comments; doc comments as convention.

Range comments are much more friendly for writing large blocks of text.
Reading the Guide, I was a bit alarmed that Rust might not have them.
Speaking of, they're very useful for doc comments, which are just a
convention for formatting comments, not a separate type of comment.
