This change also includes a formatting changing with the new rustfmt version,
but I'm expecting it to have already been applied in another patch by the time
this lands.

Look much neater. If you can fix the unrelated change that would be great.

This looks like an unrelated change. Chan you check your rust-format version ?

I've mentioned this in the commit message. I'm thinking too much in terms of changesets, not patches. Should I drop it from this patch ?

Yep, you should eitehr drop it or apply it in a different changesets. Especially because the patch that got in is pinning the formatting to the older version. So you new formatting is going to be wrong.
