Broken anchor links in new Error Handling guide

[yberreby]

In the Error Handling guide, clicking the anchor link "A brief interlude: unwrapping isn't evil" in the table of contents has no effect.

It points to: https://doc.rust-lang.org/nightly/book/error-handling.html#a-brief-interlude-unwrapping-isnt-evil

...whereas the heading's anchor is: https://doc.rust-lang.org/nightly/book/error-handling.html#a-brief-interlude:-unwrapping-isn't-evil

EDIT: it's actually worse than that - it seems all headings containing special characters (<, >, !) have broken links:

• Composing Option<T> values
• The try! macro
• The real try! macro
• Error handling with Box<Error>

The problem is apparently not limited to just headings. For example, the first sentence in the section https://doc.rust-lang.org/nightly/book/error-handling.html#the-option-type says : "The Option type is defined in the standard library" but the link provided leads to the section on pattern matching.

I'm sorry, I'll get right on that. Thanks for noticing, @filsmick.

@filsmick Thats strange, because in my local markdown viewer, all those links work.

@ChristopherDumas Yeah, the reason is because rustdoc doesn't discard special chars in sections id and href attributes.

Well, I fixed it now.

Try clicking on "Composing Option values". Looks like the fix didn't make it to stable, because it works on the nightly version

@filsmick yes, it was fixed after 1.4 was branched. 1.5 has the fix.
