Text indicates compiler errors but Ferris doesn't

[codesections]

In a few instances, the text of the book correctly notes that a provided code example will not compile. However, the corresponding code example lacks a Ferris with a question mark. For example, Ch17.3 notes that Listing 17-11 "won’t compile yet because we haven’t implemented the blog crate yet" but Listing 17-11 does not have a Ferris (or a red background). Would a PR noting these discrepancies be helpful (or, alternatively, have I misunderstood something and it is appropriate for these code samples to lack a confused Ferris)?

I havne't triple checked the source, but if they aren't marked appropriately, they won't show the ferris. it's entirely possible that we just missed the marker somewhere; the ferris feature is pretty new!

Would e-help be appreciated on this, or is it something y'all will catch on a later pass? Happy to run though the code to spot those issues, but I don't want to be a pest if getting a PR would be a bother.

I'd love a PR!

In fact, there are similar problems in chapters 05, 12, and 20 as per #1505's 1st unresolved question. The appropriate code blocks were not annotated because of the resolution in #1505 (comment) by @steveklabnik, which was:

I think leaving it purely as the status at that point is the right call.

So it is questionable whether this needs to be done. In case the decision is to show Ferris on those as well, the appropriate code blocks can be marked; one can see the different attributes used for this by opening Screenshots in the #1505 (comment).

I believe these have been resolved. Please open issues or PRs for the exact listings that are missing Ferris if you find any.
