Wrap the face-sweep repair match the way rustfmt wants it

CI's Desktop job failed at the Format step on 16f3fb4: rustfmt puts the
`match faces_without_proxy(...)` on its own line under the `let` and
re-indents its arms, and the commit was written without running it. No
code changes; only the layout of that one match in library.rs.
