Given that this removes the "TODO" comment you just added in the previous
patch, I agree with Stolee's suggestion [1] that you mention this context in
the patch 2 commit message rather than a code comment. The commit message of
*this* patch already explains the behavior you're correcting, so I don't
think any other changes would be needed here.

The rest of this looks good to me!
