Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @steveklabnik (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. The way Github handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.

execute. These

Is there a precedence in the book for double spaces after sentence ends?

[steveklabnik]

There should be only one space.

Good addition. I'd probably try to explain that --ignored is a flag on the test binary (not cargo) to avoid confusion over why there is an additional -- between test and the argument.

@adamcrume Both of @killercup 's points are valid, but I think they're small enough that if you weren't willing to make them, we can take this as-is anyway. Let me know what you think either way :)

[adamcrume]

@steveklabnik I'm happy to make the changes. I'll have free time to work on it this evening.

[killercup]

LGTM, @adamcrume.
