Applied to `rust-next` -- thanks everyone!

    [ Removed spurious `///`-to-`//` change and adjusted `line!` to match.
      Added a comment to match `file!`'s. Made `NOTE:` more precise. Reworded
      to say it is only one doctest being updated. - Miguel ]

    [ Removed generated file from `rust/.gitignore` and added it to
      `scripts/remove-stale-files`. - Miguel ]

Cheers,
Miguel
