Missing code snippet in the Error Handling guide

[swatteau]

Paragraph 6 of https://doc.rust-lang.org/nightly/book/error-handling.html#the-option-type starts with : "But wait, what about unwrap used in unwrap-double?". The problem is that there is no code sample involving something called unwrap-double. It seems that there is some piece of text missing. Moreover, the presence of a dash in the name is a little dubious.

EDIT: same thing with option-ex-string-find at the beginning of https://doc.rust-lang.org/nightly/book/error-handling.html#composing-option%3Ct%3E-values. I guess there might be other occurences of this problem in the rest of the text.

Wow. It seems like I've overlooked a ton of things.

@swatteau I figured out whats going on. In the original blog post, each code snippet was named like a file. The things he was referencing, like unwrap-double, were the names of the code snippets.

@ChristopherDumas I just skimmed the rest of the text and saw nothing else so that may well be the only two places where the problem occurs.

@ChristopherDumas This is what happens when there's a huge amount of text, it happens. :) More eyes find more bugs!

#28755 also fixed this, I believe!
